4λ O-band CW DFB Laser Chipset

Edge-emitting DFB laser diode chips, designed for CW use in CWDM4 with external modulation

 

 

 

A chipset of 4 x single mode, edge-emitting DFB laser diode chips, designed for CW use in CWDM4 with external modulation.

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.

 

Key features

  • >45mW CW operation
  • Operating temp 20°C to 70°C
  • AlInGaAs MQW active region
  • Proven high reliability – GR468 qualification
  • Suitable for non-hermetic applications

 

 

Applications

  • SiPho integrated circuits
  • 400G Ethernet
  • Datacentre interconnect
  • Telecomms
