An optical element mounting method includes: illuminating ultraviolet light onto a polymer optical waveguide device; under the ultraviolet light illumination, capturing, by an image pickup device, the polymer optical waveguide device including a light incident/exiting position of a waveguide core; and judging, from a difference between bright and dark in a captured image, that a portion brighter than other portions or a portion darker than other portions is the light incident/exiting position of the waveguide core.

A production method of an optical waveguide includes: preparing a laminated body that includes a first clad layer and at least a core layer laminated on the first clad layer; forming a light propagating optical waveguide core by cutting the core layer by use of a dicing saw from a side where the core layer is laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer; and embedding at least a cut portion of the laminated body with a second clad layer.

There is provided an optical waveguide including: a waveguide core through which light propagates; a cavity that is present inside the waveguide core so as to be open at least one end in the thickness direction of the waveguide core; a layer-form first cladding having a lower refractive index than the waveguide core, and sealing at least one of the at least one opening of the cavity to thereby close the opening of the cavity; and a second cladding having a lower refractive index than the waveguide core, and surrounding the waveguide core. There is also provided a method of manufacturing the optical waveguide.

A sub-mount includes a recess for holding a polymer optical waveguide film and recesses for embedding and holding a light emitting element and a light detecting element. The sub-mount further has an adhesive filling groove formed adjacent to respective recesses. When mounting the polymer optical waveguide film, the light emitting element, and the light detecting element onto the sub-mount, an adhesive is accurately applied and is prevented from flowing out as the adhesive filling grooves are provided.

An optical waveguide film that can supply power at extremely low cost, and a light transmission and reception module using this film are provided. A macromolecular optical waveguide film is composed of a square-shaped waveguide core which extends in a film length direction, a conductive wires which extends in the film length direction and is arranged in parallel with the waveguide core, and a cladding which surrounds the waveguide core and the conductive wire. The two conductive wires are provided, and the waveguide core is provided between the two conductive wires.

The present invention provides a bidirectional communication optical waveguide which can adopt a configuration in which light sources having the same wavelengths are used and stray light is not inputted to either a light emitting device or a light receiving device, and the bidirectional communication optical waveguide realizes a bidirectional communication module. The bidirectional communication optical waveguide includes a main waveguide core and a sub-waveguide core. A main inclined plane is provided in a midway of an optical path in the main waveguide core. The sub-waveguide core is provided with a sub-inclined plane in one end portion, and is close to or in contact with the main waveguide core such that the sub-inclined plane and the main inclined plane face each other. The main waveguide core has a structure in which an input light beam from an end portion for performing input and output of a bidirectional light signal from and to an optical fiber is deflected by total reflection at the main inclined plane and guided to the other end portion. The sub-waveguide core has a structure in which a refractive index of the sub-waveguide core is set not more than a refractive index of the main waveguide core and thereby total transmission of an output light beam from the end portion connected to a light emitting device is performed through the sub-inclined plane.
