ABSTRACT:
A photodetector carrier is disclosed which does not cause possible deterioration of an optical coupling characteristic between an optical fiber and a photodetector mounted on the carrier and is improved in high speed characteristics of the photodetector. The photodetector carrier is constructed by brazing to a metal plate of a ceramic substrate on which a photodetector mounting portion and a wiring pattern are formed. The photodetector carrier is fixed to a metal casing of a photodetector module by laser welding.
