Optical module with lens assembly directly mounted on carrier by soldering and laser diode indirectly mounted on carrier through sub-mount

摘要

An optical module is disclosed where the module includes an optical active device mounted on a carrier via a sub-mount, and a lens assembly mounted on the carrier and optically coupled with the device and an external fiber. A feature of the optical module is that the lens assembly has a metalized portion fixed to the carrier by the soldering.

主权项

1. An optical module, comprising:
at least one semiconductor optical device; at least one lens assembly optically coupled with the semiconductor optical device; and a carrier made of ceramics for mounting the optical device and the lens assembly, wherein the lens assembly has a metalized surface fixed to the carrier by a solder, wherein the carrier provides a metal layer and a heater in a portion where the lens assembly is soldered, and wherein the carrier has a hollow in a portion of a back surface opposite to a surface to mount the lens assembly, a portion of the hollow corresponding to the heater.
