Processing Interband Cascade Laser for High Temperature CW Operation

Abstract

A narrow ridge-waveguide mid-IR interband cascade laser based on Type-II InAs/GaInSh heterostructures processed with a thick gold heat spreading layer operated CW at temperatures ranging from 80 K to 214.4 K. Its differential quantum efficiency was 547% at 80 K dropped slowly to 239% at 200 K, commensurate with a T(1) of 160.2. The device had a characteristic temperature, T(0), of 40.2 K and showed signs of significant heating at temperatures above 200 K.
