Abstract

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