Abstract
There is provided a fluorine-containing resin composition which is used for nonlinear optical material and comprises (I) a fluorine-containing prepolymer and (II) an organic compound exhibiting a second- or higher-order nonlinear optical effect, in which the fluorine-containing prepolymer (I): (1) is a non-crystalline polymer having a fluorine content of not less than 25% and (2) has a carbon-carbon double bond in a polymer side chain or at an end of a polymer trunk chain and also there is provided a nonlinear optical waveguide device produced from the fluorine-containing resin composition. A suitable nonlinear optical material having a stable structure with a nonlinear substance is produced, and an excellent nonlinear optical waveguide device is produced by relatively simple steps while maintaining transparency in a near infrared region.
