Paper Abstract

In this work, modeling along with associate experiments of the broad-area laser with an external optical cavity which employs a mode-selecting mirror has been conducted to study the effects of optical feedback on the filamentation and mode control of broad-area semiconductor lasers. By using split-step FFT algorithm in a propagation mode, mode profiles of the broad-area lasers with a spherical cavity are simulated in detail, the simulation results agree very well with experimental measurements and verify the validity of the simulation model. Mode control of broad-area semiconductor lasers has also been studies through employing the same simulation model and associates experiments have also been conducted. The results will be presented in this paper.
