Abstract

A tightly interlaced chiral sculptured thin film (STF), whose unit cell comprises one structural period each of two otherwise identical chiral STFs but of opposite structural handedness, exhibits a polarization-universal bandgap on axial excitation. This bandgap lies wholly inside the Bragg regime of either constituent chiral STF.
