Description
The laser design is a ridge waveguide (RWG) grown on n-type substrate with multi-quantum well (MQW) active layers and distributed-feedback (DFB) ebeam lithography grating layer.
The devices are compatible with non-hermetic assembly, with facets coated with an anti-reflection (AR) coating at the front and high-reflection (HR) coating at the back.This product is available as a singulated die in Gel-Pak or on tape.
