Design of Corrugated Waveguide Filters by Fourier-Transform

  title={Design of Corrugated Waveguide Filters by Fourier-Transform},
    A new, approximate, corrugated waveguide filter design method is developed for thin film optical waveguides. The method determines both the corrugation period and depth, measured along the guide's surface, given a specification of the filter's reflection coefficient. The design technique is based on a combined effective index approach and Fourier transform, inverse-scattering theory for one-dimensional, dispersionless, dielectric media. Use of the general technique is illustrated by the design… CONTINUE READING
