Effective numerical integration of traveling wave model for edge-emitting broad-area semiconductor lasers and amplifiers. (English) Zbl 1259.78031

Summary: 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 Schrödinger 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.
