Two-dimensional numerical simulator for multielectrode distributed feedback laser diodes

A two-dimensional program for the analysis of multielectrode distributed feedback (DFB) laser diodes under nonuniform carrier injection conditions has been developed. The program self-consistently solves the carrier transport together with optical equations. In addition, the present simulation system offers a user-friendly graphic interface during input and output stages. The effectiveness of the program has been demonstrated through a three-section DFB LD. The improvement of the spatial hole burning effect under nonuniform carrier injection has been elucidated by directly monitoring the carrier and/or current density distribution and indirectly evaluating the cavity loss.<
