Abstract:
1. An optical module comprising: a substrate having first and second regions and first and second optical waveguides, said first and second regions being arranged along a predetermined plane, and said first and second optical waveguides being provided in said first region, and said first and second optical waveguides extending in a direction of a predetermined axis; a semiconductor light emitting device including a semiconductor light emitting element, said semiconductor light emitting device being provided in the second region, and said semiconductor light emitting element being optically coupled to said second optical waveguide; a semiconductor light receiving device including a light receiving element, said semiconductor light receiving device being provided in said first region; and an optical device including an optical element, said optical element being provided on said first region so as to reflect a part of incident light from said light emitting element to said light receiving element and so as to transmit a part of said incident light; wherein said optical element is provided between said first and second optical waveguides wherein said optical element is optically coupled to said first and second optical waveguides, wherein said optical device has a transparent substrate, wherein light from said semiconductor light emitting element can pass through said transparent substrate, wherein said transparent substrate has a pair of surfaces, each extending along a plane intersecting with said predetermined axis, and wherein one of said pair of surfaces is inclined so as to reflect a part of incident light from said light emitting element to said light receiving element.
