Paper Abstract

This work presents a model for semiconductor lasers based on digital signal analysis. This model discretizes the laser cavity, sampling the electrical field along the longitudinal direction of the cavity at fixed space intervals. The discretization of the field allows us to obtain the longitudinal spectrum of the laser. For computational efficiency, the wavelength dependence of the material gain is implemented using digital filters applied to the field samples, lumped into a single cavity. Therefore, the most complex and computationally costly operation of the algorithm is performed in a single section. Even further, due to the digital nature of the filter, we can adjust any given frequency response both in modulus and phase using the theory of discrete time signal analysis. The results of this model are compared versus standard modeling methods such as integration of the rate equations with Runge-Kutta Algorithm.
