<p><P>PROBLEM TO BE SOLVED: To provide an optical waveguide and an optical module that have a small size and a high optical coupling efficiency. <P>SOLUTION: The optical module has, in addition to a light emitting element 14 and a light receiving element 15, a planar optical waveguide 10 to which an optical fiber ribbon 7 composed of a circular plurality of optical fibers is optically coupled. This optical waveguide 10 is incorporated with a plurality of light emitting waveguide cores 11 having a vertically long cross sectional shape relative to a mounting face of the optical element which is composed of the light emitting element 14 and the light receiving element 15, and similarly incorporated with a plurality of light receiving waveguide cores 12 having a horizontally long cross sectional shape. In the end part of the optical waveguide 10, there is provided a mirror face 10a, wherein reflection of light is performed between the light emitting and light receiving waveguide cores 11, 12, and between the light emitting and light receiving elements 14, 15. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
