Abstract

2D-in-plane spontaneous emission studies reveal lateral carrier-non-pinning linked to longitudinal temperature variation in 9xx-nm broad-area-lasers. Front-side non-pinning at the stripe edges broadens far-field, eliminated with short pulses (no heat) or high front-facet reflectivity (flat optical profile).
