OPTICAL WAVEGUIDE TERMINATION APPARATUS, OPTICAL COMMUNICATION DEVICE AND METHOD FOR TERMINATING OPTICAL WAVE

摘要

Disclosed is an optical waveguide termination apparatus which comprises a disk-shaped structure waveguide. An interface is arranged on an outer side wall of the disk-shaped structure waveguide. The interface is used for being externally connected to an optical waveguide port. An optical wave emitted from the optical waveguide port is diffracted from the interface to the interior of the disk-shaped structure waveguide and is propagated along an inner side wall of the disk-shaped structure waveguide until being reduced and terminated. Accordingly, also disclosed is an optical communication device. By means of the present invention, an optical wave emitted from an optical waveguide port can be terminated, thereby preventing the optical wave from being reflected back to the optical waveguide port, and the present invention has the characteristics of small space occupation and low costs.
