Abstract
We evaluated the temperature dependence of the internal quantum efficiency of 1.5-mu m-wavelength GaInAsP/InP compressively-strained 20-nm-wide quantu m-wire lasers from the cavity length dependence of the differential quantum efficiency. As a result, high internal quantum efficiency eta(i) similar t o 1.0 was obtained at T < 200 K, which decreased with an increase in temper ature.
