The temperature dependence of the internal loss ..cap alpha.. of the InGaAsP/InP buried crescent laser is presented in the temperature range 20--80 /sup 0/C. ..cap alpha.. is about 18 cm/sup -1/, and no apparent temperature dependence of ..cap alpha.. is observed in this temperature range. This indicates that the temperature-sensitive behavior of the threshold current in InGaAsP/InP long-wavelength lasers is not due to the temperature dependence of internal loss. The decrease in the external quantum efficiency with increasing temperature is attributed to the decrease in the internal quantum efficiency.
