Title:
OPTICAL WAVEGUIDE STRUCTURE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/125799
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 has excellent durability. Further disclosed is an electronic apparatus provided with the aforementioned optical waveguide structure. One embodiment of the present disclosures is cited below. The optical waveguide structure (1) is provided with: an optical waveguide body (2) that forms a block shape; and five light-emitting elements (61-65). The optical waveguide body (2) is formed from a plurality of cladding layers and a plurality of core layers being laminated in a predetermined order. In each core layer, a predetermined pattern of core sections (94) and cladding sections (95) is formed. The core sections (94) are portions that form a light path for transmitted light, and are three-dimensionally disposed within the optical waveguide body (2). The core sections (94) have as a primary material a resin composition containing, for example, a norbornene resin, and are formed to a desired shape by selectively radiating actinic radiation to the core layer (93) configured from a material of which the refractive index changes by means of irradiation by actinic radiation and also by means of heating.
