Abstract

Semiconductor lasers subject to optical feedback have been investigated systematically for the past two decades for understanding the mechanism responsible for coherence collapse and low frequency fluctuations In these studies typically the external cavity length has been 10 centimeters or longer[1]. It was always found that the basic instability emerges through a supercritical Hopf bifurcation. However shorter cavities are experimentally realizable, and some recent numerical work has shown novel dynamical behavior for these cavities[2].
