ABSTRACT:
A semiconductor laser module of the present invention comprises a semiconductor laser, a pig tail optical fiber, a optical part, and a transition metal doped optical fiber. The optical part optically couples the semiconductor laser and the pig tail optical fiber to each other. The transition metal doped optical fiber is formed in a length corresponding to an attenuation amount with which desired distortion characteristics and desired noise characteristics are realized, and is connected to the side of the pig tail optical fiber opposite to the side which faces the semiconductor laser. The distortion characteristics of the semiconductor laser is improved by the action of the transition metal doped optical fiber. Consequently, the yield of semiconductor laser modules is improved.
