Abstract

Novel multi-active region semiconductor lasers with large coupled optical cavity and high quantum efficiency has been proposed and fabricated. The external and differential quantum efficiency are 2.9 and 3.0 W/A, and the output light power is /spl sim/5W when the injecting current equals 2A for the four active region 980 nm strained InGaAs/GaAs QW lasers. The fundamental mode light output with perpendicular angle /spl les/17/spl deg/ for this type of large coupled optical cavity laser has been achieved.
