Abstract: We demonstrate GaSb-based interband cascade lasers (ICLs) emitting around 3.65 mu m, which exhibit a room-temperature continuous-wave (CW) output power above 100 mW. Cavity-length analysis showed that the laser structure has a low internal loss of 3 cm(-1) while maintaining a total internal quantum efficiency greater than one. After 6400 h CW operation at 25 degrees C, the threshold current of the laser increased by 3%, and the output power decreased by 7%, indicating good reliability of the device.
