    摘要： A method of fabricating a polymer optical circuit is provided. The method includes structuring a mold with a main mold and an auxiliary mold. The main mold has a first concavity corresponding to a first portion of the waveguide core, a second concavity corresponding to an end portion of the waveguide core with a specific shape, an injection hole for injecting a resin into the concavities, and a suction hole for suctioning-out the resin. The auxiliary mold has a shape corresponding to the specific shape of the end portion of the waveguide core. The method also includes firmly sticking a clad base film to a surface of the mold where the concavities are formed; filling the concavities with resin by injecting the resin via the injection hole and suctioning the resin via the suction hole; and forming the waveguide core by curing the resin.

    摘要： An optical transmission unit of an optical reception and transmission module holds a first end portion of the optical waveguide film on the first holding member so that light emitted from the light emitting device is coupled to an incident end surface of the optical waveguide. An optical reception unit holds a second end portion of the optical waveguide film on the second holding member so that light emitted from an emitting end surface of the optical waveguide is received by the light receiving device. At least the optical waveguide film is covered with flame-retardant resin having flame retardancy of HB or higher according to a UL-94 test and a minimum bending radius of the optical waveguide film covered with the flame-retardant resin and having a flame-retardant resin layer formed on its surface is from 1 mm to 3 mm.

    摘要： The present invention provides an optical waveguide, which at least includes: a waveguide core having a cavity therein; and a clad which encloses the periphery of the waveguide core and has a smaller refractive index than the waveguide core, wherein the optical waveguide changes a direction of a part or all of propagated light by using a part or all of an interface between the waveguide core and the cavity as a reflecting surface. The present invention further provides a method for manufacturing the optical waveguide, which at least includes: forming a core having a cavity therein on a substrate; applying an uncured clad material to a side surface and an upper portion of the core while maintaining the cavity which allows an atmospheric gas to be present in the cavity; and curing the clad material by heat or light to seal the gas in the cavity.
