Large range electrically-induced reflection notch tuning in polymer stabilized cholesteric liquid crystals

Author affiliations

Abstract

This communication reports large magnitude (exceeding 1500 nm) and reversible reflection notch tuning in polymer stabilized cholesteric liquid crystals (PSCLCs) formulated with negative dielectric anisotropy (−Δε) hosts upon application of a direct current (DC) field. Selective and repeatable tuning ranges of 100 nm to 400 nm are demonstrated. The reflection changes are dictated by a nonlinear distortion of the pitch across the cell thickness, which is associated with electromechanical displacement of the polymer stabilizing network. The electro-optical control of the selective reflection in −Δε PSCLCs may have potential use in optics, displays, and other commercial products.
