Presentation details

Previous research has shown that semiconductor lasers (SL) can be driven to chaotic regime by applying either optical injection or feedback process. Here we combine both, so that the feedback affects the SL, as well as, the electronic branch of the system. By the means of bifurcation diagram and correlation time, we numerically demonstrate from two different schemes how the chaos is induced for lower feedback levels or amplified for feedback strengths for which the system was already chaotic.
