ABSTRACT:
Homopolymers and copolymers with an acrylic backbone chain having pendant side-chains containing a nitrone functional group undergo change in refractive index upon exposure to actinic radiation. Waveguides are "written"in films containing such polymers by exposing predtermined areas to sufficient actinic radiation to change the refractive index.
