Abstract :
High-power 1.06 mu m double channel planar buried-heterostructure (DCPBH) lasers have been fabricated by liquid-phase epitaxy. AT 20 degrees C, the threshold current is 80 mA and CW output powers of 20 mW can be obtained. Under pulsed operation, quantum efficiencies of 0.37 W/A per facet and maximum pulse output powers of 150 mW are realised, while maintaining the lowest-order spatial mode and a symmetrical far-field distribution.
