Photoluminescence (PL) of separate confinement heterostructure, single quantum well (SCH-SQW) laser material provides a quantitative evaluation of the quality of AIGaAs grown by organometallic vapor phase epitaxy. There is a good correlation between

Wide stripe semiconductor lasers can be used as optical power amplifiers for obtaining high power single spatial mode output beams. Anti-reflection coatings deposited on the facets of semiconductor lasers effectively suppress any self-oscillation. Th

A compact self-aligning laser radar has been constructed for coherent ranging and velocimetry using a laser diode modulated by feedback from light scattered from a diffusing target. The phenomenology of beat-signal generation in the device is discuss

Continuous wave surface emitting distributed feedback lasers without facet reflections were fabricated which produced up to 25 mW of cw power and 200 mW of pulsed power at room temperature. The devices operated in a single spatial and single spectral

The rigorous Floquet-Block mode expansion1 used in the past to discuss off-resonance grating waveguide coupling is extended to the on-resonance condition using the method of grating eigenfunctions.2 The results of this theory are applied to a discuss
