    Comprehensive measurements of the differential quantum efficiency (ηd ) dependence on the active layer thickness (d) for 1.55 μm InGaAsP buried crescent (BC) injection lasers are presented. The results show that ηd increases rapidly as d decreases. The strong d dependence of ηd in...

    The nonlinear generation of a difference mode in an injection laser is considered. A new design based on the InGaP/GaAs/InGaAs heterostructure is suggested in order to generate two laser modes with a wavelength of about 1 �m and a difference mode at a wavelength of about 10 �m. In...
