Connecting structure of optical module and optical connector

Abstract

To make connection work be done easily and certainly, and, further, space-saving be achieved, when an optical fiber and an optical module are connected. An optical module includes a connecting face connected with an optical connector and a first diffraction grating, provided in an end part of a first optical waveguide, to convert an optical axis direction of the first optical waveguide to a direction toward an opposing face of the optical connector; in the optical connector, the second optical waveguide is provided in the optical connector along the opposing face toward the connecting face; the optical connector includes a second diffraction grating, provided in an end part of the second optical waveguide, to convert an optical axis direction of the second optical waveguide into a direction toward the optical module; and while the optical module and the optical connector are connected mechanically to make the opposing face of the optical connector oppose the connecting face of the optical module, the first diffraction grating and the second diffraction grating opposing each other and being coupled optically.
