            Abstract : 
Integrated optical devices, S-bends and Y-splitters, have been fabricated in the poly(methylmethacrylate/2-methacryloylethylmethacrylate) copolymer system (P(MMA/MAOEMA)) by direct UV writing. This fabrication technique uses a UV-induced refractive index change without additional etching. Y-splitter junction losses of 0.4 dB and a splitting ratio of 50 ± 1% were obtained.
