Abstract
The dynamics of a broad area semiconductor vertical-cavity
surface-emitting laser (VCSEL) is analytically and numerically
investigated considering the linewidth enhancement factor resulting in
the modulation instability of a spatially homogeneous generation mode.
We find the aperture width depends on the parameters of the laser
system, above which the modulation instability leads to chaotic
filamentalization of the optical field and complicates the practical
application of such lasers. We show that using the external optical
injection of small amplitude, it is possible both to transform chaotic
filaments into regular stationary spatial optical structures (stripes
and hexagons) and to stabilize the broad-area VCSELs.
