Abstract
A bidirectional optical communication module using a single optical fiber is disclosed. The module includes an optical fiber having a cut-away surface polished to have an acute angle between the cut-away surface and an axis of the optical fiber, a semiconductor laser emitting a transmission light coupled with a light fiber core, and a bidirectional optical device having a light receiving portion absorbing a receiving light outputted from the light fiber core for thereby optically coupling a bidirectional optical device in which a light receiving device is integrated into a light transmitting semiconductor laser as a single chip and an optical fiber when fabricating an optical module for implementing a light signal transmission and receiving operation using one optical fiber.
