The properties of quantum dot lasers comprising a single layer of InGaAs dots set in a single GaAs quantum well 100 angstroms wide in a waveguide core region of Al 0.15Ga 0.85As with cladding layers of Al 0.6Ga 0.4As were studied. Measurements were made of the optical absorption, optical mode loss and gain spectra as a function of temperature by single pass technique using a device with a segmented contact. All measurements were made under pulsed conditions.
