High Power DFB Lasers for FMCW LIDAR

Frequency-modulated continuous wave (FMCW) lasers at 1310nm/1550nm. Enabling improved LIDAR system performance, safety and range, at low cost, and low power consumption.

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.
