Title

Polymer-Stabilized Cholesteric Liquid Crystal For Polarization-Independent Variable Optical Attenuator

Keywords

Liquid crystal; Polymer; Variable optical attenuator

Abstract

A reflective-type polymer-stabilized cholesteric liquid crystal (PSCLC) cell was demonstrated at λ = 1550nm laser wavelength. It showed a high attenuation range (∼30dB), a low operating voltage (∼12 V rms), a highly efficient polarization-independent behavior and flat wavelength dependence in the range of 1525-1575 nm. The combined effects of curing temperature, chiral dopant, and monomer concentration were investigated and optimized to maximally improve the PSCLC properties. The potential application of PSCLC as a polarization-independent variable optical attenuator is emphasized.
