Abstract
Previous work has reported that polymer stabilized cholesteric liquid crystals (PSCLCs) have shown dynamic photonic properties with the application of direct current (DC) field, including bandwidth broadening, switchable scattering, red tuning and blue tuning. Recently, we have prepared holographic polymer stabilized cholesteric liquid crystals reflection gratings (H-PSCLCs). High order diffraction peaks, such as the second or/and third order diffraction peaks, are observed from the H-PSCLC samples written with a 363.8 nm Argon laser. The higher order reflection bands are caused by the deformed helical structure of the polymer stabilizing network formed under reflection grating conditions. The spectral position of the second-order reflection band is simply adjusted by chiral dopant concentrations in the CLC mixture. The selective main and higher order reflection notches can be red-tuned and broadened by the application of DC fields.
