Photonic computing is widely used to accelerate the computational performance in machine learning. Photonic decision making is a promising approach utilizing photonic computing technologies to solve the multi-armed bandit problems based on reinforcement learning. Photonic decision making using chaotic mode-competition dynamics has been proposed. However, the experimental conditions for achieving a superior decision-making performance have not yet been established. Herein, we experimentally investigate mode-competition dynamics in a chaotic multimode semiconductor laser in the presence of optical feedback and injection. We control the chaotic mode-competition dynamics via optical injection and observe that positive wavelength detuning results in an efficient mode concentration to one of the longitudinal modes with a small optical injection power. We experimentally investigate two-dimensional bifurcation diagram of the total intensity of the laser dynamics. Complex mixed dynamics are observed in the presence of optical feedback and injection. We experimentally conduct decision making to solve the bandit problem using chaotic mode-competition dynamics. A fast mode-concentration property is observed at positive wavelength detunings, resulting in fast convergence of the correct decision rate. Our findings could be useful in accelerating the decision-making performance in adaptive optical networks using reinforcement learning.

The Multi-Armed Bandit (MAB) problem, foundational to reinforcement learning-based decision-making, addresses the challenge of maximizing rewards amid multiple uncertain choices. While algorithmic solutions are effective, their computational efficiency diminishes with increasing problem complexity. Photonic accelerators, leveraging temporal and spatial-temporal chaos, have emerged as promising alternatives. However, despite these advancements, current approaches either compromise computation speed or amplify system complexity. In this paper, we introduce a chaotic microresonator frequency comb (chaotic comb) to tackle the MAB problem, where each comb mode is assigned to a slot machine. Through a proof-of-concept experiment, we employ 44 comb modes to address an MAB with 44 slot machines, demonstrating performance competitive with both conventional software algorithms and other photonic methods. Furthermore, the scalability of decision making is explored with up to 512 slot machines using experimentally obtained temporal chaos in different time slots. Power-law scalability is achieved with an exponent of 0.96, outperforming conventional software-based algorithms. Moreover, we find that a numerically calculated chaotic comb accurately reproduces experimental results, paving the way for discussions on strategies to increase the number of slot machines.

Photonic accelerators have attracted increasing attention for use in artificial intelligence applications. The multi-armed bandit problem is a fundamental problem of decision making using reinforcement learning. However, to the best of our knowledge, the scalability of photonic decision making has not yet been demonstrated in experiments because of the technical difficulties in the physical realization. We propose a parallel photonic decision-making system to solve large-scale multi-armed bandit problems using optical spatiotemporal chaos. We solved a 512-armed bandit problem online, which is larger than those in previous experiments by two orders of magnitude. The scaling property for correct decision making is examined as a function of the number of slot machines, evaluated as an exponent of 0.86. This exponent is smaller than that in previous studies, indicating the superiority of the proposed parallel principle. This experimental demonstration facilitates photonic decision making to solve large-scale multi-armed bandit problems for future photonic accelerators.

Photonic artificial intelligence has attracted considerable interest in accelerating machine learning; however, the unique optical properties have not been fully used for achieving higher-order functionalities. Chaotic itinerancy, with its spontaneous transient dynamics among multiple quasi-attractors, can be used to realize brain-like functionalities. In this study, we numerically and experimentally investigate a method for controlling the chaotic itinerancy in a multimode semiconductor laser to solve a machine learning task, namely, the multiarmed bandit problem, which is fundamental to reinforcement learning. The proposed method uses chaotic itinerant motion in mode competition dynamics controlled via optical injection. We found that the exploration mechanism is completely different from a conventional searching algorithm and is highly scalable, outperforming the conventional approaches for large-scale bandit problems. This study paves the way to use chaotic itinerancy for effectively solving complex machine learning tasks as photonic hardware accelerators.

Photonic computing has been intensively studied to explore the ultrahigh bandwidth of lightwaves. However, electronic support is indispensable for the post-processing and control of photonic systems owing to the difficulties encountered in all-optical processing. Herein, we demonstrate an ultrafast silicon circuitry capable of conducting thresholding operations on incoming chaotically oscillating high-bandwidth signals. Such circuits are critical elements in ultrafast random-number generators and photonic reinforcement learning that exploit chaotically oscillating time series. The circuit design, including active inductors for bandwidth expansion, and proof-of-principle fabricated device operations are demonstrated using a 180 nm silicon complementary metal–oxide–semiconductor technology node.

Abstract
Accelerating artificial intelligence by photonics is an active field of study aiming to exploit the unique properties of photons. Reinforcement learning is an important branch of machine learning, and photonic decision-making principles have been demonstrated with respect to the multi-armed bandit problems. However, reinforcement learning could involve a massive number of states, unlike previously demonstrated bandit problems where the number of states is only one. Q-learning is a well-known approach in reinforcement learning that can deal with many states. The architecture of Q-learning, however, does not fit well photonic implementations due to its separation of update rule and the action selection. In this study, we organize a new architecture for multi-state reinforcement learning as a parallel array of bandit problems in order to benefit from photonic decision-makers, which we call parallel bandit architecture for reinforcement learning or PBRL in short. Taking a cart-pole balancing problem as an instance, we demonstrate that PBRL adapts to the environment in fewer time steps than Q-learning. Furthermore, PBRL yields faster adaptation when operated with a chaotic laser time series than the case with uniformly distributed pseudorandom numbers where the autocorrelation inherent in the laser chaos provides a positive effect. We also find that the variety of states that the system undergoes during the learning phase exhibits completely different properties between PBRL and Q-learning. The insights obtained through the present study are also beneficial for existing computing platforms, not just photonic realizations, in accelerating performances by the PBRL algorithms and correlated random sequences.

Reinforcement learning involves decision-making in dynamic and uncertain environments and constitutes a crucial element of artificial intelligence. In our previous work, we experimentally demonstrated that the ultrafast chaotic oscillatory dynamics of lasers can be used to efficiently solve the two-armed bandit problem, which requires decision-making concerning a class of difficult trade-offs called the exploration-exploitation dilemma. However, only two selections were employed in that research; hence, the scalability of the laser-chaos-based reinforcement learning should be clarified. In this study, we demonstrated a scalable, pipelined principle of resolving the multi-armed bandit problem by introducing time-division multiplexing of chaotically oscillated ultrafast time series. The experimental demonstrations in which bandit problems with up to 64 arms were successfully solved are presented where laser chaos time series significantly outperforms quasiperiodic signals, computer-generated pseudorandom numbers, and coloured noise. Detailed analyses are also provided that include performance comparisons among laser chaos signals generated in different physical conditions, which coincide with the diffusivity inherent in the time series. This study paves the way for ultrafast reinforcement learning by taking advantage of the ultrahigh bandwidths of light wave and practical enabling technologies.

Bulletin of the Japan Society for Industrial and Applied Mathematics, Volume:23, Number:1, First page:11, Last page:20, 2013
This paper reviews a secret key distribution based on 'Bounded Observability.' First, the secret key agreement from correlated sources is introduced. Next, the notion of Bounded Observability is introduced. This notion means the practical difficulty of completely observing physical phenomena that are too fast, or too large, or too complex. Finally, a secret key distribution scheme by using correlated physical randomness in lasers driven by common random light is introduced.

We investigate generalized synchronization and complexity in unidirectionally coupled Rössler systems and Mackey-Glass systems with time-delayed feedback. The generalized synchronization is measured by using two identical response systems which are driven by a common drive system. To measure the complexity, KS entropy and KY dimension are calculated quantitatively from the Lyapunov spectrum by using the linearized equations. The response systems show generalized synchronization for large coupling strengths. The entropy and dimensionality decrease as the coupling strength is increased. The minimum value of entropy is obtained at the condition of generalized synchronization, whose value corresponds to the entropy for the solitary drive system, even though the temporal waveforms of the drive and response systems are significantly different. The maximum entropy is achieved outside the region where generalized synchronization is achieved, whose value almost corresponds to the sum of those of the two solitary drive and response systems. It is found that the coupling effect changes the entropy within these two values. The dimensionality decreases monotonically even within the region of generalized synchronization.

We experimentally and numerically investigate consistency of response output in a Nd: YAG microchip laser driven repeatedly by chaos and colored noise with different bandwidths. An increase of consistency is observed as the amplitude, of the drive signal is increased for both chaos and colored noise drive signals. After reaching an optimal value the consistency begins to decrease due to the deterministic dynamics of the nonlinear response as shown by the change in sign of the conditional Lyapunov exponent.

We investigate transient dynamics of synchronized low frequency fluctuations (LFFs) in mutually coupled semiconductor lasers. We observe repeated spontaneous switching of leader-laggard relationship in two lasers. We found that the relationship between the optical frequencies of the two lasers decides the leader laser with sudden intensity dropouts of LFFs. We explain this phenomenon by using an analysis of steady state solutions in the Lang-Kobayashi equations that describe the dynamics of semiconductor lasers. We found that the optical frequency of the leader laser attracts the optical frequency of the laggard laser while the trajectories of the two lasers wander many steady state solutions, and spontaneouts switching of leader-laggard relationship occurs. We also found that sudden intensity dropouts occur at the maximum gain mode obtained from the analysis of steady state solutions in a solitary laser with optical feedback.

We investigate instantaneous behaviors of the leader-laggard relationship of temporal waveforms in mutually-coupled two semiconductor lasers in the open-loop configuration. The temporal waveform of one laser output is delayed with respect to that of the other laser output by the propagation delay time, and the leader-laggard relationship can be determined by measuring cross correlation between the two temporal waveforms with time delay. The leader can be identified on average when the optical carrier frequency of the leader laser is higher than the other laser. However, when short-term cross-correlation is measured and the local structure of the leader-laggard relationship is investigated, spontaneous exchange between the leader and laggard lasers can be observed in time, even for fixed initial optical frequency detuning. These numerical results agree with our experimental observation.

Recently, fast physical random-number generators using chaotic lasers have been proposed. However, most previous schemes using chaotic lasers schemes are bulky to implement. Random number generation using a photonic integrated circuit (PIC) with 10-mm-long external cavity for fast chaos generation has been demonstrated. In this study, we investigated the condition for generating fast random numbers for different sampling rates using a PIC with 5-mm-long external cavity. We also used PICs with different external cavity lengths and generated random bit sequences at various sampling rates. We can generate random bits at rates up to 5.56 Gb/s using a PIC with 4-mm-long external cavity.

IEICE technical report. Nonlinear problems, Volume:113, Number:116, First page:105, Last page:110, 08 Jul. 2013
Semiconductor lasers with time-delayed optical feedback have infinite dimensionality in general. The methods for estimating Lyapunov exponents have not been established yet. In this study, we propose a method for calculating the maximum Lyapunov exponent in semiconductor lasers with time-delayed optical feedback by using generalized synchronization. The maximum Lyapunov exponent is numerically estimated and compared with the exponent calculated from the linearized Lang-Kobayashi equation. The maximum Lyapunov exponents calculated by using the two methods are almost identical. This method can be applied for the estimation of the maximum Lyapunov exponent in experimental systems.

Lyapunov exponents represents a exponential expansion (construction) rate of a infinitesimal perturba-tion to an orbit of a dynamical system, which are asymptotic values over an attractor of the system. Finite-time Lyapunov exponents have been proposed to quantify the exponential expansion (construction) rate for finite orbits. We can obtain some information which is useful for classification of chaos dynamics, chaos control, and prediction. However, a method for calculation of the finite-time Lyapunov exponents in time-delayed dynamical systems have not been well established yet because of the difficulty of calculating Lyapunov exponents in time-delayed high-dimen-sional systems. We present a method for calculating the finite-time Lyapunov exponents in time-delayed dynamical systems, and apply it to a Mackey-Glass model, an optpelectromc feedback laser system and a Lang-Kobayashi equation for a semiconductor laser with optical feedback. We investigate standard deviation of the finite-time Lya-punov exponents for the variation of a delay time and a length of a orbit. It is found that the standard deviation approaches to zero as finite time L, and this approach is as L-v.

Local Lyapunov exponents can be used to evaluate local stability of dynamical systems in phase space. In time-delayed dynamical systems, the techniques for calculating local Lyapunov exponents have not been well established, even though some examples of the calculation of the averaged Lyapunov exponent have been reported. We propose a method to calculate local Lyapunov exponents in time-delayed dynamical systems and evaluate the validity of the method by using a model of a semiconductor laser with time-delayed optical feedback.

Recently it has been proposed that optical devices can be used to generate correlated random bit sequences and that secure key distribution is possible using the correlated random bit sequences. We report the first experimental demonstration of a scheme for generating correlated random bit sequences, using semiconductor lasers synchronized by common random optical signals. The correlated random bit sequences generated in this scheme can be used by two legitimate users to create information-theoretically secure keys.

Consistency of response in a system driven repeatedly by a complex signal has been observed in many nonlinear dynamical systems. Consistency could be applied for physical one-way function for information security. We investigate the consistency of coupled semiconductor lasers with optical feedback and measure the complexity of the coupled laser system by using Lyapunov spectrum. The complexity of coupled lasers increases with the increase of a coupling strength, however, the complexity decreases suddenly when consistency is achieved under strong coupling strength.

We experimentally observe the synchronization in semiconductor lasers subject to a common drive signal with constant-amplitude random-phase. We show the parameter regions at which the outputs of the two response lasers can be highly correlated with each other even though the correlation between the drive and response lasers is very low.

We experimentally demonstrate random bit generation using multi-bit samples of bandwidth-enhanced chaos in semiconductor lasers. Chaotic fluctuation of laser output is generated in a semiconductor laser with optical feedback and the chaotic output is injected into a second semiconductor laser to obtain a chaotic intensity signal with bandwidth enhanced up to 16 GHz. The chaotic signal is converted to an 8-bit digital signal by sampling with a digital oscilloscope at 12.5 Giga samples per second (GS/s). Random bits are generated by bitwise exclusive-OR operation on corresponding bits in samples of the chaotic signal and its time-delayed signal. Statistical tests verify the randomness of bit sequences obtained using 1 to 6 bits per sample, corresponding to fast random bit generation rates from 12.5 to 75 Gigabit per second (Gb/s) (= 6 bit × 12.5 GS/s).

Random number generators in digital information systems exploit physical entropy sources, such as electronic and photonic noise, to add unpredictability to deterministically generated pseudo-random sequences. However, there is a large gap between the generation rates achieved with existing physical sources and the high data rates of many computation and communication systems, which is a fundamental weakness in these systems. We show that good-quality random bit sequences can be generated at very fast bit rates using physical chaos in semiconductor lasers. Streams of bits which pass standard statistical tests for randomness have been generated at rates of up to 1.7 gigabit per second by sampling the fluctuating optical output of two chaotic lasers. This rate is an order of magnitude faster than that of previously reported devices for physical random bit generators with verified randomness.

We experimentally observe the generation and synchronization of bandwidth-enhanced chaos in a semiconductor laser that is subject to optical injection from a second chaotic semiconductor laser with optical feedback. Effective bandwidth enhancement is achieved over 12GHz outside the injection locking range. Synchronization of chaos with a bandwidth greater than 12GHz is observed between the second and a third lasers under the injection locking condition. High-quality chaos synchronization is observed within the injection locking range.

Vertical-cavity surface-emitting lasers (VCSELs) have been considered as novel devices for optical communications and wireless local area networks. In this study, we experimentally investigate of generation and synchronization of chaos in mutually coupled VCSELs with two time delays. We observe three kinds of different RF spectra and find that the couple strength ratio of two time delays is responsible for the RF spectra.

Many nonlinear dynamical systems have an ability to generate consistent outputs when driven by a repeated external signal. Consistency is defined as the reproducibility of response waveforms in a nonlinear dynamical system driven repeatedly by a signal, starting from different initial conditions of the system. Consistency of dynamics is essential for information transmission in biological and physiological systems and for reproduction of spatiotemporal patterns in nature. We experimentally investigate consistency of response output in a microchip solid-state laser and a Mackey-Glass electronic circuit driven repeatedly by chaos and colored noise.

We experimentally observe synchronization of two semiconductor lasers commonly driven by a chaotic semiconductor laser subject to optical feedback. Under condition that the relaxation oscillation frequency is matched between the two response lasers, but mismatched between the drive and the two response lasers, we show that it is possible to observe strongly correlated synchronization between the two response lasers even when the correlation between the drive and response lasers is low. We also introduce separate optical feedback to the two response lasers. The maximum correlation between the two response lasers is obtained when the phase of the feedback light is matched between the two response lasers, while the minimum correlation is observed when the difference in the optical phase is π.

We experimentally and numerically demonstrate the dual synchronization of chaos in two pairs of one-way coupled Mackey-Glass electronic circuits with time-delayed feedback. The output of the two drive circuits are mixed and used both for the feedback signal to the two drive circuits and for the transmission signal to the two response circuits. We investigate the regions for achieving dual synchronization of chaos when the delay time is mismatched between the drive and response circuits.

We experimentally observe consistency in a Mackey-Glass electronic circuit (MGC) repeatedly driven by a colored noise signal. We discovered that, multiple consistent response signal patterns are observed by driving the MGC with colored noise. To confirm our experimental observations, we use a numerical model for consistency of MGC. We found that consistency is obtained at large drive signals. More than one type of response waveform patterns are observed, which we call multiple basins of consistency.

We experimentally observe synchronization of chaos in two mutually-coupled vertical-cavity surface-emitting lasers (VCSELs). We observe polarization-resolved temporal waveforms and find in-phase and anti-phase synchronization of chaos under the condition of injection locking. We investigate leader-laggard relationship between two chaotic waveforms of mutually coupled VCSELs and find that the laser with longer wavelength becomes the leader. The leader-laggard relationship is related to the characteristics of injection locking in optically coupled VCSELs.

We numerically investigate the detailed characteristics of chaos synchronization in semiconductor lasers subject to polarization-rotated optical feedback. The emission of the dominant TE mode of a drive laser is rotated 90 degrees and fed back to the laser with time delay. The polarization-rotated TE mode is also injected with time delay into the TM mode of a second laser. Two types of synchronization with different time-lags are found, as in the case for synchronization in semiconductor lasers with non-rotated optical feedback. However, a significant difference to the non-rotated optical feedback case is that neither of the two types of synchronization requires matching of optical carrier frequency between the two lasers.

Characteristics such as temperature dependence of the critical current and space distribution of the order parameter of step edge type Josephson junction were analyzed by use of two dimensional Ginzburg-Landau equation. We found that the solution could be expressed by use of the Jacobian elliptic function. The relationship between the supercurrent and phase difference φ is proportional to sinφ.

Secure communications with chaotic lasers have attracted increasing interests all over the world. We overview recent technologies of secure communications with chaotic lasers. We describe some techniques for message encoding and decoding based on synchronization of chaos. We quantitatively evaluate the degree of security for the techniques of secure communications with chaos. A new approach to secure communications using chaos based on information theoretic security is described.

We experimentally demonstrate the dual synchronization of chaos in two pairs of Nd: YVO_4 microchip lasers in a one-wat coupling configuration over one transmission channel. Dual synchronization is achieved when the optical frequency is matched between the corresponding pairs of lasers by using injection locking. Under the condition of the injection locking between both of the master lasers and the slave lasers, the injection locking is alternately achieved and the accuracy of dual synchronization is degrated.

We have experimentally demonstrated chaos synchronization in two Nd:YVO_4 microchip lasers by using optical injection. Since the condition of the chaos synchronization is strongly dependent on the injection locking range, it is easy to synchronize chaos of the master laser with that of unauthorized lasers if the optical frequencies are matched to each other. To improve the disadvantage, we have proposed a new chaos-synchronization method based on incoherent feedback to the pumping power by using the value proportional to the difference between the peak heights of the electrical amplitude in two laser outputs. We can achieve narrow tolerable region of chaos synchronization even if there exists parameter mismatching between the two lasers, because this method requires the matching of population inversion between the two lasers instead of electrical fields without injection locking effect.

Random number generators play a crucial role for applications in information security and large-scale computer simulations. Pseudo-random number generators have periodicity and reproducibility, which are vulnerable for encryption keys in information security and reduce the accuracy of computer simulations. In this study, we develop physical random number generators using fast chaotic semiconductor lasers. We quantitatively evaluate the entropy rate of chaotic temporal waveforms to certify the unreproducibility of physical random number generators. We experimentally succeed in developing a module of a real-time physical random number generator using a photonic integrated circuit and an FPGA electronic board.

We demonstrate ultra-fast random number generation based on chaotic dynamics in semiconductor lasers. We generate bandwidth-enhanced chaos with unidirectionally-coupled semiconductor lasers and use it for ultra-fast random number generation. The generated random numbers pass statistical tests of randomness. We succeed in generating random numbers at the maximum generation rate of 1.2 Tb/s. We also demonstrate random number generation using photonic integrated circuits for miniaturization.

Grant amount(Total):27430000, Direct funding:21100000, Indirect funding:6330000
We experimentally demonstrated fast random number generation using chaotic semiconductor lasers. Chaotic fluctuation of laser output is generated and converted into binary sequences for random number generation. Statistical tests verify the randomness of bit sequences generated in the experiment. We succeeded in generating random bit sequences at rates up to 400 Gb/s. We also achieved the estimation of entropy rate and demonstrated quantum cryptography experiment with the random number generator.
