    摘要： 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.

    摘要： The present invention provides an optical waveguide manufacturing method. A polymer resin with different refractive index from the polymer film is applied to a polymer film and is cured, so that a double-layered polymer film, which has a cladding layer and a core layer with higher refractive index than the cladding layer, is manufactured. The core layer is cut by the dicing saw having a blade for enabling cutting of a resin layer, so as to be processed into core portions of the optical waveguide. Cut concave portions of the core layer are filled with polymer resin having the same refractive index with the cladding layer. The core portions are further covered with the polymer resin, and the polymer resin is cured so that a cladding resin layer is formed.

    摘要： 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.
