OPTICAL COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the costs of a surface mount type reception module, a transmission module, and a transmission and reception module more. SOLUTION: This optical communication device comprising an optical fiber, an optical component, and a substrate for optical coupling is characterized by that the coupling part between one side of the optical fiber and the optical component is fixed by a semiconductor substrate having a V groove formed by etching and part of the opposite side of the optical fiber is fixed by a holding substrate different from the semiconductor substrate.
