Abstract :
A wave-optical model is used to investigate filamentation of the optical field in conventional double heterostructure and quantum well semiconductor lasers. The field is propagated by the Crank-Nicholson method, and the gain model is based on a semiclassical laser theory that contains the effects of cross relaxation due to electron-electron and electron-phonon collisions. The model predicts that for broad-area devices, quantum well lasers are less affected by filamentation than conventional double heterostructure lasers
