39.2: Invited Paper : Stimuli‐Responsive Cholesteric Liquid Crystal Composites for Optics and Photonics

Abstract Stimuli‐induced control of the reflection notch of cholesteric liquid crystals (CLCs) is potentially useful in optics, photonics, and displays. This report briefly reviews and describes a series of related results in which we have observed symmetric bandwidth broadening and reflection notch tuning in polymer stabilized CLCs (PSCLCs) upon application of a DC field. The electro‐optic responses are typically observed in the presence of polymer stabilization, in formulations based on negative dielectric liquid crystals hosts, and when subjected to DC field.
