“…Semiconductor lasers, due to their high-speed performance, superior controllability, high energy density, and high spatial resolution, have become an essential tool in the study of optical spiking neurons. It has been demonstrated that semiconductor lasers can display a variety of properties that are similar to those observed in neuronal systems, including excitability [12][13][14] and nonlinear dynamics [15,16]. These studies lay solid groundwork for the evolution of photonic neuromorphic computing and pave the way for the realization of more efficient low-power computing methods.…”

In this paper, a method of generating controllable spikes utilizing symmetric semiconductor ring lasers (SRLs) is investigated, and various optical behaviors of biological neurons are successfully emulated on a faster timescale. We demonstrate the synchronized spike phenomena in two directions, generated in both the clockwise (CW) and counterclockwise (CCW) modes of the tunable laser (TL)-injected SRL. The size of the peaks and the interval between them can be manipulated by adjusting the output complex amplitude of the TL and bias current. At the same time, we also analyzed the CW mode of the TL-injected SRL and successfully replicated the four distinct discharge patterns of biological neurons. These findings offer promising prospects for future neuromorphic research.

“…Moreover, the operation of the dynamic system can be adjusted by means of the feedback systems [55]. Feedback is also used in controlling the dynamic systems with various modulation types [56][57][58]. Another use of feedback is to achieve wavelength stability [59] of wavelength division multiplexing (WDM) systems through the adjustment of cross-correlation level by setting up the DC bias current [60].…”

Four-tone small signal analysis was performed for a nonlinear optoelectronic feedback laser diode system. In the analysis, Volterra power series up to second-order opening, the second kernel for the output intermodulation distortion (IMD) analysis was performed. The components of the alternative IMD frequency were selected for analysis. These are the four IMD frequency components. The variation of IMD frequency component amplitudes was investigated under various values of delay-time (t0) and the feedback gain constant (K). The feedback values and the critical frequencies, at which the coherence collapse or chaos occur, were also determined.

Edge-emitting semiconductor laser driven by a van der Pol oscillator: analytical and numerical analysis

A device constituted of an edge-emitting semiconductor laser driven by a van der Pol oscillator is studied analytically and numerically. For small value of the parameter controlling the dissipation in van der Pol oscillator, the Lindstedt-Poincaré method is used to find analytically high accurate solutions of the van der Pol equation with a bias term. Then by using the harmonic balance method, we obtain the amplitude of the oscillatory states of the laser output. The analytical results are compared with those from numerical simulation and a good agreement is obtained. By varying the parameter controlling the dissipation in van der Pol oscillator and the normalized reverse bias saturation of the injection current in the laser, we numerically show that the laser output exhibits a period-doubling route to chaos. The coexistence between periodic and chaotic behaviors is found in edge-emitting semiconductor laser driven by a van der Pol oscillator for specific parameters values. It is demonstrated that the edge-emitting semiconductor laser driven by a van der Pol oscillator generates dynamical behaviors found in edge-emitting semiconductor laser subject to a sine modulated current demonstrating the advantage of using a simple and less bulky electronic device to modulate the semiconductor laser pump current.
