Dynamic simulations of integrated couped cavity lasers

We propose a general procedure that we used for the design of semiconductor integrated coupled cavity lasers taking advantage of the Photon-Photon Resonance effect to increase their direct modulation bandwidth. The procedure, based on an analysis at threshold of the longitudinal complete cavity modes, is combined with dynamic simulations of the lasers small and large signal modulations. As an example, we report the study of the bandwidth extension in two mutually coupled cavity DBR lasers.
