Abstract

We demonstrate experimentally that diffraction of light incident obliquely at the oblique helicoidal cholesteric (ChOH) structure results in scattering at both the half- (P/2) and the full pitch (P) periodicities. Transmission spectra at P and P/2 are observed in the Vis spectral range, tunable by the electric field and the angle of light incidence. Diffraction at P/2 shows two distinct spectral bands for p- and s-polarized incident light. Diffraction at P is a single wide band. Unique optical properties of ChOH are attractive for applications such as electrically tunable band-pass filters, optical rotators, and beam-steering devices.
