Paper Abstract

Threshold characteristics of compressively strained InAlAsSb 3 - 4 micrometers MQW lasers have been studied theoretically. The Auger coefficient dependence on the QW composition has been calculated. It is shown that the internal absorption decreases with strain, which results in weaker temperature dependence of the threshold carrier concentration. It is demonstrated that the strain considerably improves threshold characteristics of InAlAsSb QW laser and increases its limiting operation temperature.
