Abstract

See full text

An optical module includes: at least one optical waveguide provided on a surface of a substrate; a plurality of grooves provided in the optical waveguide on the surface of the substrate and having both a surface orthogonal to the surface of the substrate and an inclined surface; multiple pairs of light-emitting and light-receiving elements aligned with the plurality of grooves in the optical waveguide and provided so as to correspond to light of different wavelengths on the optical waveguide; and a plurality of light-selecting filters each provided on an inclined surface of the plurality of grooves in the optical waveguide and reflecting light of the wavelength corresponding to the light-emitting element in the respective pair of light-emitting and light-receiving elements towards the optical waveguide, and selectively reflecting light of the corresponding wavelength from the light propagating through the optical waveguide towards the corresponding pair of light-emitting and light-receiving elements.
