Abstract

A light emitting unit including a light emitting device of a light emitting module for optical communication is constituted by a laser diode for emitting communication light, a sub-mount having a good thermal conductivity and holding the laser diode on its upper surface, a heat sink for removing the heat generated by the laser diode, a photodiode for monitoring a light output from the laser diode, a laser driver IC which is thermally isolated from the laser diode, has an electric contact placed near the electric contact of the laser diode and connected thereto by wire bonding, and drives the laser diode, and a metal package for holding the heat sink, the photodiode, and the laser driver IC. A light emitting module for optical communication uses the light emitting unit.
