ABSTRACT:
There is provided a material which can give a high elasticity and heat resistance to an optical waveguide member by photo-curing while maintaining transparency in a near infrared region and further makes it possible to use a film forming process by a spin coating method and a process for producing a waveguide by photolithograph, to obtain a waveguide having a large area and to produce an optical waveguide having reduced water absorption, and further there can be provided an optical waveguide member and an optical waveguide device. Namely, there are provided a fluorine-containing optical waveguide material comprising a curable fluorine-containing prepolymer (I) which is a non-crystalline polymer having a fluorine content of not less than 25% by weight and has a carbon-carbon double bond in a polymer side chain and/or at an end of a polymer trunk chain, an optical waveguide member which is a cured article of the optical waveguide material and an optical waveguide device comprising the optical waveguide member.
