High-Performance 1.5-µm Distributed Feed Back Lasers with Strained Multi-Quantum Well Structure Grown by Metalorganic Molecular Beam Epitaxy (Chemical Beam Epitaxy)

Abstract
The Metalorganic Molecular Beam Epitaxy (Chemical Beam Epitaxy) technique was used to make active layers for Distributed Feed Back (DFB) lasers. Typical characteristics of these lasers-for example a threshold current of 6 mA and a slope efficiency of 0.3 mW/mA per facet-reflect the high homogeneity and high uniformity of the grown layers. The values referred here are the best ever reported for a CBE-grown active layer.
