High temperature GaInSbAs/GaAlSbAs quantum well singlemode continuous wave lasers emitting near 2.3 /spl mu/m

Narrow ridge 5 /spl mu/m-wide GaInSbAs/GaAlSbAs quantum well (QW) lasers emitting in the continuous wave (CW) regime at temperatures up to 130/spl deg/C have been fabricated. The CW threshold current varied between 20 and 35 mA at room temperature (RT). The lasers operated in the fundamental spatial mode and exhibited single longitudinal mode emission over a wide range of CW operation conditions. The emission wavelength increased from 2.26 /spl mu/m at RT up to 2.43 /spl mu/m at 124/spl deg/C. The CW output optical power reached 45 mW/facet at 22/spl deg/C and exceeded 10 mW/facet at 100/spl deg/C.
