摘要： 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.
