GaInAsSb/AlGaAsSb lasers in the wavelength range between 2.73 mu m and 2.93 mu m

摘要

Compressively strained multiple quantum well lasers in the GaInAsSb/AlGaAsSb material system are reported. Indium concentrations between 40% and 47.5% were chosen for the GaInAsSb quantum wells. Compressive strains varied between 1.16% and 1.43%. The lasers worked continuous wave at room temperature up to a wavelength of 2.81 mum. For a laser with 2.93 mum wavelength continuous wave operation was found up to a temperature of -23degreesC. This laser worked in pulsed operation at 15degreesC. (C) 2003 Elsevier B.V.
