1.3 µm DFB Chip in TO Can for Wide-Temperature 10Gb/s Uncooled applications up to 20km

Currently Viewing:

The Broadcom TO293K is an hermetic sealed TO can device with a photo diode for optical output monitoring using 1310nm single mode edge-emitting laser diode chip for use in uncooled applications up to 10.7Gb/sec. The laser is mounted into a TO header and hermetic sealed with a specific lens cap. The laser design is a Ridge Waveguide on n-type substrate with multi-quantum well (MQW) active layers and distributed-feedback (DFB) grating layer.
