Journal ArticleDOI
Design, fabrication, and performance of infrared and visible vertical-cavity surface-emitting lasers
TL;DR: A review of the basic experimental structures of VCSELs is given in this paper, with emphasis on recent developments in distributed Bragg reflectors, gain media, as well as current and optical confinement techniques.
Journal ArticleDOI
Room-temperature direct current operation of 290 nm light-emitting diodes with milliwatt power levels
Arthur J. Fischer,Andrew A. Allerman,Mary H. Crawford,K. H. A. Bogart,S. R. Lee,Robert Kaplar,W.W. Chow,Steven R. Kurtz,K. W. Fullmer,Jeffrey J. Figiel +9 more
TL;DR: In this paper, the active region is composed of three Al0.36Ga0.64N quantum wells with Al 0.48 Ga0.52N barriers for emission at 290 nm.
Journal ArticleDOI
Theory of semiconductor quantum-dot laser dynamics
W.W. Chow,Stephan W. Koch +1 more
TL;DR: In this paper, a theory for describing nonequilibrium dynamics in a semiconductor quantum-dot laser is presented, which is applied to a microcavity laser with a gain region consisting of an inhomogeneous distribution of quantum dots, a quantum well wetting layer, and injection pumped bulk regions.
Journal ArticleDOI
Scalability of small-aperture selectively oxidized vertical cavity lasers
TL;DR: In this paper, the authors analyzed the threshold properties of small area selectively oxidized vertical cavity lasers and showed that the optical loss can be reduced for laser with areas as small as 0.25 μm2 while maintaining sufficient transverse optical confinement by displacing the apertures longitudinally away from the cavity and reducing the oxide thickness.
Journal ArticleDOI
Piezoelectric effects on the optical properties of GaN/AlxGa1−xN multiple quantum wells
TL;DR: In this article, the optical properties of GaN/AlGaN multiple quantum wells (MQWS) have been investigated by picosecond time-resolved photoluminescence (PL) measurements.
