Appreciably large differential quantum efficiency Ωdf with one-directional output operation was obtained in 1.5 μm distributed reflector (DR) lasers, using a thin active layer of 50 nm and the SCH structure. Ωdf of the DR lasers was experimentally confirmed to be two times that of DFB lasers cleaved from the same wafer, which indicated high efficiency and high power characteristics of DR lasers.
