Reflective SOA for Tuneable Lasers

Sub Header Required



8x edge-emitting DFB laser diode array designed for CW use in CW-WDM-MSA compliant applications.

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 a hermetic anti-reflectance layer on the front facet and a high reflectance coating on the rear facet.

This product is available to be purchased as a singulated die in Gel Pak or tape.
