ABSTRACT:
An optical module100comprises a substrate110at which V-shaped groove110aand110bare formed through etching to extend along directions perpendicular to each other and a cube-type wavelength division multiplexer150that allows light to be transmitted or reflected on a 90° angle depending upon the wavelength of the light, lens elements140aand140bconstituted of silicon, a light emitting element120that emits light to be directed to the outside via a lens element and the wavelength division multiplexer and a light receiving element130that receives incoming light from the outside via the wavelength division multiplexer and a lens element, all disposed on the substrate. The components, which contribute to miniaturization of the module, can be mounted all together on a single substrate and thus, the mass productivity is greatly improved and the module can be offered at a more affordable price.
