Paper Abstract

In this work we present the dynamic behavior of a two laterally coupled semiconductor lasers using numerical integration and circuit modeling of the array rate equations. We have obtained the same dynamic behavior when the system becomes stable. In this situation we can validate the conditions of the circuit model of such a device developed by the authors. By comparing the results obtained from direct numerical integration of the rate equation for the photon and carrier densities and the circuit response through a SPICE base program we have obtained the same bandwidth with both methods. The results show as well that the system presents unstable behavior for definite regimes of operation with agreement of both methods of analysis.
