MATHEMATICAL AND NUMERICAL ANALYSIS OF THE SPREADING RESISTANCE OF SEMICONDUCTOR BURIED RIDGE STRIPE LASERS

Abstract

A 2D numerical simulation using a finite element technique is presented for computing spreading resistance of a semiconductor buried ridge stripe laser. The simplified physical model is analyzed from the functional analysis point of view and a proof of existence and uniqueness of the nonlinear partial differential equations obtained from this simplified model is given. The discrete associated nonlinear problem is solved on triangular finite elements using conjugate gradient algorithms. Some results are presented for a specific semiconductor laser
