An optical switch module for aligning and fixing an optical fiber array relative to an optical switch device includes an optical fiber support member for fixing the optical fiber array; a first support device forming a homo-junction with the optical fiber support member and including a first thermal deformation buffer device; and a second support device forming a hetero-junction with the first support device to support the first support device and including a second thermal deformation buffer device.

Optical switch module having a buffer device for minimizing a post welding shift

A method for correcting or hammering a deformation which occurs in the multi-channel optoelectronic module and is caused by a post welding shift. The multi-channel optoelectronic module has an optical fiber support member for supporting an optical fiber array. The method includes the steps of: assembling the multi-channel optoelectronic module by using a laser welding process; and forming at least one welded portion on a predetermined position of said optical fiber supporting member corresponding to the deformation to thereby recover the deformation by using a shrinkage effect of the welded portion.

Method for laser hammering a multi-channel optoelectronic device module

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.
