Parasitic effects in the period doubling of semiconductor lasers

In this paper we study the behavior of a single mode semiconductor laser under strong signal modulation. To describe the semiconductor laser, we employed the standard rate equation model, commonly used for this type of analysis. A continuation method is used in order to study the evolution of the behavior of the laser as the modulation index is increased. The bifurcation points are determined using Floquet Theory. In order to introduce the parasitic effects, we have used the equivalent circuit model. First, the intrinsic model is used to verify the results obtained with the continuation method and after, we introduce the laser parasitics to obtain new results on the dynamic behavior.
