| 摘要 |
An optical communication module for communicating a light signal including a groove portion (16) whose section is V-shaped and provided on the surface of an optical waveguide substrate (10), on one of two surfaces of which groove portion (16) a mirror (20) is formed by the coating with a metal film and in the vicinity of the other surface of which groove portion (16), a tip (14) of an optical waveguide (11) on the optical waveguide substrate (10) is provided, whereby a signal light guided by the optical waveguide (11) is reflected by the mirror (20) of the metal film so as to be incident on a light-receiving element (30) disposed on the surface of the optical waveguide substrate (10). <IMAGE> <IMAGE> |
