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.
具有丙烯酸骨架链和含有亚硝基官能团的侧链的同聚物和共聚物在暴露于光致辐射下会发生折射率变化。在含有这样的聚合物的薄膜中,通过将预定区域暴露于足够的光致辐射下以改变折射率来“书写”波导。
