Abstract
In this work, a first report on fabricating an asymmetric Bragg coupler-based filter on polymeric waveguides without input-waveguide grating was revealed. The fabrication process we developed was using holographic interference techniques, capillary effect, soft lithography, and micro molding process. The transmission dip of about -9.2 dB and the 3 dB transmission bandwidth of about 0.125 nm were obtained from a filter.
