Abstract
CDH-LOC lasers with tight current confinement to the lasing region provide CW output powers as high as 165 mW. The overall power conversion efficiency in CW operation reaches values of 35% (front-facet emitted power/overall input electrical power). Single-longitudinal-mode and fundamental-mode operations are achieved to 40 mW CW and 60 mW peak power (50% duty cycle), respectively. The threshold-current temperature coefficient T0 reaches values of 185 K.
