1.3 µm FP Chip in TO Can for Wide-Temperature 10Gb/s Uncooled applications to 1km

Currently Viewing:

The Broadcom TO295J149x is an hermetic sealed TO can device with integral photo diode for optical output monitoring using 1490nm single mode edge-emitting laser diode chip for use in uncooled applications up to 2.7Gb/sec. It supports 1490nm transmission for use in passive optical networks (PON). The laser is mounted into a TO-56 header and hermetic sealed with a specific lens cap. The laser design is a capped mesa buried hetero-structure (CMBH) grown on n-type substrate with multi-quantum well (MQW) active layers and distributed-feedback (DFB) grating layer. The facets are coated with an anti-reflectance layer on the front facet and a high reflectance coating on the rear facet.
