摘要
We experimentally study the spatial and temporal characteristics of filamentation in broad-area semiconductor lasers, Near-field measurements show that the spacing between filaments decreases as either the pumping level or the linewidth-enhancement factor is increased, Spectral measurements reveal that spatial filaments are accompanied by periodic or chaotic temporal variations, Our experimental results show excellent qualitative agreement with a theory based on a linear stability analysis of the rate equations for an infinitely wide stripe laser.
