Laser diode module and method of manufacturing the same

Abstract

A laser diode (LD) device 3 is mounted and fixed on a device mounting stand 2. A lens 5 on a tip side of a lensed fiber 8 fixed on a ferrule 4 and the LD device 3 are opposingly arranged. Centers of the lensed fiber 8 and the LD device 3 are aligned, in which state, the ferrule 4 is held and fixed from both sides of the ferrule 4 by a ferrule fixing components 6 and 7 on a side close to the LD device 3 and a side distant from the LD device 3, respectively. A hold-fixing part 11 of the ferrule 4 on the side distant from the LD device 3 is fixed to the ferrule fixing component 7 using a solder material 10. An inexpensive laser diode module with high long-term reliability can be provided which can be manufactured easily in a short time.
