Abstract

A Fabry-Perot description of the three-layer spectral-hole filter (SHF) fabricated using sculptured thin-film technology is presented. The identical outer layers are made of a thin-film helicoidal bianisotropic medium, and individually act as Bragg reflectors of one circular polarization. The middle layer, made of a homogeneous, isotropic, dielectric medium, functions as a quarter-wave spacer layer at the center-wavelength of the Bragg regime. The measured transmittance spectrums of the fabricated SHF are evaluated relative to exact theoretical results.
