Title:

OPTICAL WAVEGUIDE STRUCTURE AND ELECTRONIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2011/125939

Kind Code:

A1

Abstract:

Disclosed is an optical waveguide structure that has a wide degree of freedom of pattern shape design, can form a core section (light path) having high dimensional precision via a simple method, and is provided with an optical waveguide having excellent durability. Further disclosed is an electronic apparatus. One embodiment of the present disclosures is cited below. The optical waveguide structure (1) is provided with: an optical waveguide (9) formed from laminating a cladding layer (91, 92) on both surfaces of a core layer (93); conductor layers (51, 52) joined to both surfaces thereof; a light-path transformation unit (96) that bends the light path of the optical waveguide (9) nearly perpendicularly; and a light-emitting element (10) and an electric element (12). The core layer (93) has a core section (94) and cladding sections (95). The core section (94) is formed in a desired shape by means of selectively radiating light to the layer, which is configured from a composition containing: (A) a cyclic olefin resin, (B) at least one of either an oligomer having a cyclic ether group or a monomer having a cyclic ether group and having a refractive index that differs from the aforementioned A; and (C) a photoacid generator.
