High Power DFB Lasers for FMCW LIDAR

Frequency modulated continuous wave (FMCW) lasers  enabling the next generation of LIDAR technology 

 

 

 

Frequency modulated continuous wave (FMCW) lasers at 1310nm/1550nm. Enabling increased performance, safety and range, whilst enabling low cost, low power solutions for LIDAR.  

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.
