High-power 1.3-µm InGaAsP/InP laser diodes are desirable in various fields such as long-haul optical communication systems, optical time domain reflectometers, and satellite communication systems. We have achieved stable high-power operation as high as 50 mW of 1.3-µm InGaAsP/InP p-substrate buried crescent laser diodes (PBC-LDs)1 by controlling the Iront- and rear-tacet reflectivities of laser chips.
