Abstract
Strained layer GaSbAs-GaAs quantum wells have the potential for longer emission wavelengths than InGaAs-GaAs quantum wells even though Eg(GaSb)>Eg(InAs) and the lattice mismatch is worse. Longer wavelength (lower energy) emission is possible because of the large valence band discontinuity. In this work we report the growth and operation of strained layer GaSbAs-GaAs quantum-well lasers.
