FLUORINE-CONTAINING MATERIAL FOR OPTICAL WAVEGUIDE

Title:

FLUORINE-CONTAINING MATERIAL FOR OPTICAL WAVEGUIDE

Document Type and Number:

WIPO Patent Application WO/2002/073255

Kind Code:

A1

Abstract:

A fluorine-containing material used for fabricating an optical waveguide member having a high elasticity and a high heat resistance by optical curing while maintaining the transparency in the near-infrared region, enabling use of a film-forming process by spin-coating and use of a waveguide fabrication process by optical lithography, and used for fabricating an optical waveguide having a large area and reduced water absorption properties. The material is characterized in that the material is made of a curing fluorine-containing prepolymer (I), the fluorine-containing prepolymer (I) is an amorphous polymer (1) the fluorine content of which is 25 weight% or more, and (2) which has a carbon-carbon double bond in a polymer side chain and/or at a polymer main chain end. A member for an optical waveguide made of the cured material and an optical waveguide device comprising the member are also disclosed.
