Abstract

Optical injection is a well-known technique for generation of RF oscillations in semiconductor lasers. Injecting the light of an external master laser of power P_ML into the slave laser cavity allows tuneable periodic, aperiodic and pulsing dynamics to be generated [1,2]. In the latter case, pulses are known to arise around the saddle-node (SN) bifurcation when the slave is temporarily driven away from locking by small perturbations [3].
