Abstract

The fabrication of quantum cascade (QC) laser from Group III-V (GaAs/ AlGaAs and InAlAs/InGaAs/InP) heterostructure for infra-red emision was analyzed. The emission wavelengths of QC lasers was varied over a remarkably wide range by adjustment of the thicknesses of individual heterostructure layers. The process leaves approximately 1-2μm of single crystal silicon wafer on top of the silicide which provided a high quality surface for epitaxial growth of the virtual substrate and heterostructure layers.
