Optical transmitter module

摘要

An optical transmitter module includes light-emitting devices with coaxial type packaging. Coplanar anode and cathode electrodes of one light-emitting device are mounted on a substrate so that heat generated from the light-emitting device can be effectively dissipated through the substrate. Furthermore, the direct electric connection between the light-emitting device and the substrate eliminates the requirement of wire boding for electric connection, increasing the performance of the optical transmitter module in high speed signal operation.
