Abstract
In this paper, the influences of incoherent optical feedback on the nonlinear dynamical characteristics of an optically injected semiconductor laser (SL) have been investigated numerically. Based on the bifurcation diagram of the extrema of peak series, it can be found that, after introducing incoherent optical feedback, the nonlinear dynamics of an optically injected SL will follow different routes to chaos oscillation. Period-doubling pulsing route and quasi-periodic pulsing route have been observed, which are different from that found in an optically injected SL without incoherence optical feedback. Mappings of
dynamic states in the parameters space are plotted for different incoherence feedback strengths. Compared with an optically injected SL without incoherent optical feedback, a larger expansion of chaos region is observed.
