ABSTRACT:
The present invention is to provide an optical module that installs a laser diode and a Peltier device, and to provide a method for manufacturing the optical module. The invention may relax the restriction of the solder used in the assembly thereof and may prevent the thermoelectric device from degrading the performance and the reliability thereof. The laser module includes a base, the thermoelectric device, and the carrier. The thermoelectric device is fixed to the base with a first solder, while the carrier is fixed to the thermoelectric device with a second solder whose melting point is smaller than the melting point of the first solder. When the first solder is melted to fix the thermoelectric device, the second solder is also melted to fix the carrier on the thermoelectric device.
