Abstract

In this paper, we report the optical and structural properties of a bilayer circular filter fabricated by a glancing angle deposition technique. The bilayer circular filter is realized by a two-layer <TEX>$TiO_2$</TEX> helical film with layers of opposite structural handedness. It is found that the bilayer circular filter reflects both right and left circularly polarized light with wavelength lying in the Bragg regime. The microstructure of the bilayer circular filter is also investigated using a scanning electron microscope.
