Paper Abstract

The prototypes of high-efficiency SLDs with COD threshold of more than 5•106 W/cm2 were investigated. Single spatial mode samples with 4 μm-wide active channel exhibited CW output power of more than 200 mW. Preliminary reliability tests at 100 mW level were successful. It was shown that in double-pass operation mode achieved using SM fiber reflector, external efficiency can be increased significantly. The estimations show that multimode SLD with 20-30 μm active channel width based on the same QW heterostructure may ensure reliable enough operation at output power level of more than 0.5W.
