Claim Text:
1. An optical module comprising: at least one optical waveguide provided on a surface of a substrate; a plurality of grooves provided on the at least one optical waveguide on the surface of the substrate; a plurality of light emitting and light receiving element pairs positioned on the plurality of grooves of the at least one optical waveguide, wherein each light emitting and light receiving element pair respectively corresponds to a different wavelength of light of a plurality of wavelengths of light; a plurality of optical pins provided in each of the plurality of light emitting and light receiving element pairs and disposed in the plurality of grooves of the at least one optical waveguide, each of the plurality of optical pins being configured to allow light exiting from a light emitting element and light entering a light receiving element to pass through, each of the plurality of optical pins being provided with an inclined surface on an upper end on a side opposite to a lower end, wherein the inclined surface is inclined to turn, when light from an optical waveguide is reflected on the inclined surface, the reflected light to a light receiving element, and to turn, when light from a light emitting element is reflected, the reflected light to an optical waveguide; and a light selecting filter provided on each of the inclined surfaces of the plurality of optical pins, wherein each light selecting filter is configured to reflect light of a corresponding wavelength exiting from the light emitting element of the corresponding light emitting and light receiving element pair, select light of the corresponding wavelength from propagation light propagated through the at least one optical waveguide, and reflect light to the light receiving element of the corresponding light emitting and light receiving element pair, respectively.
