A physics-based three-dimensional model for distributed feedbacklaser diodes

摘要

A comprehensive physics-based three-dimensional (3-D) model forndistributed feedback (DFB) lasers is developed and presented. The modelnconsiders self-consistently optical confinement, carrier transport andnheat transfer over the two-dimensional (2-D) cross section. It alsonaccounts for the longitudinal spatial hole-burning effect along thenlaser cavity. A rigorous optical gain model is incorporated into the 3-Dnmodel. A number of novel techniques are used in implementation of thenmodel for efficient simulation of de and ac performance. The simulatornruns efficiently on a personal computer and can be incorporated as partnof the computer-aided engineering tools for the design and analysis ofnDFB lasers
