Abstract

See full text

Embodiments of the present invention provide optical modules which input and output wavelength multiplexed optical signals to and from an optical waveguide, and a manufacturing method thereof. In one embodiment, an optical module comprises light emitting and light receiving element pairs that are positioned on grooves of one or more optical waveguides, where each light emitting and light receiving element pair corresponds to a different wavelength of light. Each light emitting and light receiving element pair includes an optical pin comprising an inclined surface and a light selecting filter that are configured to reflect light of a corresponding wavelength from an optical waveguide to the light receiving element, and from the light emitting element to the optical waveguide.
