A high gain GRIN-SCH MQW optical semiconductor laser amplifier

Abstract
A description is presented of the fabrication of a multiple-quantum-well GRIN-SCH traveling-wave-type amplifier combined with a tapered waveguide and a window region to reduce optical reflection at both end facets. Optical fiber-to-fiber gain of 10.4 dB (signal gain of 24.4 dB) under gain variation of 100 nm and gain variation was
