Abstract

Semiconductor lasers are efficient light sources with an important drawback, the lack of an intrinsic mode selection mechanism which leads to spatio-temporal instabilities. The modulation instability that unstabilizes the homogeneous solution can be suppressed by the introduction of spatial modulations in the transverse and longitudinal directions. The present work applies this stabilization technique to two of the most popular semiconductor devices, the Broad Area Semiconductor (BAS) amplifier and the Vertical-Cavity Surface-Emitting Laser (VCSEL).
