OPTICAL COMMUNICATIONS DEVICE

摘要

The invention reduces the costs of a surface mounting type receiver module, transmitter module, and transmitter and receiver module. In an optical communication device comprising an optical fiber, optical parts, and a substrate for optical coupling, the coupling portion between the end portion of the optical fiber and the optical parts is fixed by a semiconductor substrate having a V groove made by etching, and a portion of the optical fiber other than the end portion is fixed by a retaining substrate which is different from the semiconductor substrate.
