Research Abstract

We have investigated the stability of a cholesteric blue phase having three-dimensional periodic structure and functional application based on optically isotropic characteristics of the blue phase. The stabilization of cholesteric blue phases upon doping nanoparticles into blue phase liquid crystal has been achieved and its mechanism has been tried to be clarified through the study on the particle-concentration and phase dependences of the stabilization effect. We have proposed a polarization-independent refractive index modulator using optically isotropic blue phase and demonstrated the dual frequency switching for the improvement of the device performance.
