The crosslinkable poly (maleimide-co-methacrylate) s were synthesized using a pentafluorophenylmaleimide (an optical loss reducer), two methacrylate derivatives (refractive index controllers), and a glycidylmethacrylate (a crosslinker). These copolymers exhibited good thermal stability and could be thermally crosslinked by heat treatment. The refractive indexes of the copolymers could be precisely controlled by the variation of comonomer feed ratio, which was in the range of 1.45 similar to 1.49. These copolymers had very low birefringence of 6 x 10(-4) similar to <1 x 10(-4). These copolymers were crosslinked by contact printing and then developed by wet etching to obtain high quality waveguide pattern.
