Abstract

Following V-grooved,1 and T-shaped2 quantum wire (QWR) lasers, ridge QWR lasers have been achieved recently which lased at 4.7 K up to room temperature.3 To investigate the lasing mechanism and their lower-dimensional nature than quantum well (QW) lasers, we have studied spectra, emission patterns, and polarization of both their stimulated and spontaneous emission using microphotoluminescence (micro-PL) imaging method4 with short-pulse optical pumping.
