Paper Abstract

An analysis of intensity filamentation in a broad area semiconductor laser having an optical cavity with an angled grating has been performed, using both an analytical six-wave mixing theory and beam propagation method (BPM) simulations. With the grating at the Bragg diffraction angle, the analytical theory shows that the use of the grating gives rise to lateral optical anisotropy, which suppresses filamentation of the laser radiation. For a given semiconductor laser design and operating condition, the predictions of the analytical theory are compared with those from a beam propagation method simulation. 12
