Optical module producing method and optical module

摘要

The present invention provides a optical module comprising a semiconductor laser diode for outputting a laser beam; a first carrier on which the semiconductor laser diode is fixedly mounted; a photodiode for receiving a monitoring laser beam outputted from the back face of the semiconductor laser diode; a second carrier on which the photodiode is fixedly mounted; and a base on which the first and second carriers are fixedly mounted through soldering. At least one soldering sheet for soldering the first and second carriers on the base is fixedly pre-mounted on the base in place through spot welding.
