Abstract
Strain-overcompensated multiple-quantum-well (MQW) laser structures ha ve been analyzed theoretically as well as experimentally far the first time, Strain overcompensation reduces the bandgap shrinkage that norm ally takes place at the facets of compressively strained layers becaus e of strain relaxation. This results in a lower absorption of the lase r spot leading to a remarkable improvement of the reliability of high- power Baser diodes.
