1490-DFB-2.5 is a 1490nm single mode edge-emitting DFB laser diode chip, designed for use at 2.5Gb/s.

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 facets are coated with an anti reflectance layer on the front facet and a high reflectance coating on the rear facet.
