Excitability in a semiconductor laser with saturable absorber
Sylvain Barbay, Robert Kuszelewicz, Alejandro M. Yacomotti · Optics Letters · 2011
We show that a monolithic and compact vertical cavity laser with intracavity saturable absorber can emit short excitable pulses. These calibrated optical pulses can be excited as a response to an input perturbation whose amplitude is above a certain threshold. Subnanosecond excitable response is promising for applications to novel all-optical devices for information processing or logical gates.
