title: Polymeric multi-channel bandpass filters in phase-shifted Bragg waveguide gratings by direct electron beam writing.
abstract: We apply direct electron beam writing to fabricate corrugated sidewall Bragg gratings in polymer waveguides and demonstrate multi-channel passband filters based on a phase-shifted design. Experimental results are compared with numerical fittings to analyze the impact of signal polarization and waveguide cladding material upon device performance.
