Effective numerical integration of traveling wave model for edge-emitting broad-area semiconductor lasers and amplifiers

Abstract

We consider a system of 1 + 2 dimensional partial differential equations which describes dynamics of edge-emitting broad area semiconductor lasers and amplifiers. The given problem is defined on the unbounded domain. After truncating this domain and defining an auxiliary 1 + 1 dimensional linear Schröinger problem supplemented with different artificial boundary conditions, we propose an effective strategy allowing to get a solution of the full problem with a satisfactory precision in a reasonable time. For further speed up of the numerical integration, we develop a parallel version of the algorithm. © Vilnius Gediminas Technical University, 2010.
