Abstract

We theoretically investigate the propagation characteristics of inhibited spiking dynamics between two unidirectionally coupled VCSEL-based photonic neurons. The results show that, the inhibition of spiking regimes in a transmitter VCSEL (T-VCSEL), in response to the arrival of external perturbation, can be propagated to another receiver VCSEL (R-VCSEL) and two VCSEL-based photonic neurons have similar responses to the external perturbation. With increasing perturbation strength, the spikes with higher amplitude and lower oscillation frequency can be observed during the perturbation time. The spikes can be entirely suppressed for enough perturbation strength. Additionally, the spiking inhibition window can be controlled through adjusting perturbation duration.
