UV-Writing of a Superstructure Waveguide Bragg Grating in a Planar Polymer Substrate
We report on the fabrication of a superstructure Bragg grating in a planar polymer substrate. Based on a twofold illumination process an integrated waveguide and a superstructure Bragg grating are subsequently written into bulk polymethylmethacrylate by UV-induced refractive index modification. The...
