Optical module and optical transceiver installing the same

摘要

An optical transmitter module installing a thermo-electric controller (TEC) is disclosed. The optical module has a rectangular box portion as a package made of a multi-layered ceramics, within which the TEC is installed. The TEC has electrodes through which a current to driver the TEC electrically is provided. The module has a feature that the electrodes of the TEC is directly in contact with a pad provided in the back surface of the multi-layered ceramic housing.

主权项

1. A transmitter optical module, comprising:
an optical transmitting device to emit light; a thermo-electric controller (TEC) to control a temperature of the optical transmitting device, the TEC providing a top plate, a bottom plate, and a plurality of Peltier elements put between the top plate and the bottom plate, the TEC including a pillar through which a current driving the Peltier elements is supplied, the bottom plate having an area wider than an area of the top plate; and a box portion enclosing the optical transmitting device and the TEC therein, the box portion including a ceramic layer having an electrical pad facing the pillar of the TEC, wherein the pillar of the TEC is provided in an area of the bottom plate not overlapping with the top plate and directly in contact with the electrical pad on the ceramic layer without using any bonding wires.
