Refractory period of an excitable semiconductor laser with optical injection

11 Jul 2016 Garbin Bruno Dolcemascolo Axel Prati Franco Javaloyes Julien Tissoni Giovanna Barland Stéphane

Injection-locked semiconductor lasers can be brought to a neuron-like excitable regime when parameters are set close to the unlocking transition. Here we study experimentally the response of this system to repeated optical perturbations and observe the existence of a refractory period during which perturbations are not able to elicit an excitable response...
