Abstract

Optical gain spectra of quantum well gallium antimony based lasers were studied. The temperature and current dependence of modal gain and internal loss were measured by spatial filtering technique. Results of direct measurement were compared with the results of calculations for ridge-waveguide devices. Two-color lasing in a range of currents and temperatures was observed. The optical gain was found to depend upon quasi-Fermi level separation associated with optical transitions.
