    摘要: In the optical waveguide which comprises a core layer to be an optical transmission region and an upper clad layer and a lower clad layer covering the surrounding of the core layer and of which the upper clad layer is formed while being shrunk in the volume, a stress moderating layer formed a material with a smaller storage modulus than that of the upper clad layer is formed between the upper clad layer and the lower clad layer in at least a portion of a region where the upper clad layer and the lower clad layer are brought into contact with each other.

    摘要: Disclosed herein is an optical waveguide comprising a core layer to be an optical transmission region, an upper clad layer and a lower clad layer covering the core layer, in which the core layer, the upper clad layer and the lower clad layer are formed from resin materials, characterized in that a microlens made of a material having a higher refractive index than that of a material constituting said core layer is disposed in the vicinity of an end face of said core layer.
