Document Type and Number:

WIPO Patent Application WO/2017/022719

Kind Code:

A1

Abstract:

A resin optical waveguide is provided with a core, under-cladding having a lower refractive index than the core, and over-cladding. The resin optical waveguide is characterized in that a core exposure section in which the core is exposed and the over-cladding is not present is provided to one end side of the resin optical waveguide. The resin optical waveguide is also characterized by comprising a core vicinity area in which the part of the under-cladding corresponding to the core exposure section satisfies the conditions (1) and (2) indicated below. (1) The core vicinity area is an area within a distance x from the core and x is 5-20 µm. (2) The core vicinity area has a refractive index distribution in which the refractive index on the interface side with the core is higher and the refractive index on the distal side with respect to the interface with the core is lower.
