摘要 :

Liquid crystal (LC) phase is a meso-phases existing between crystalline solid and isotropic liquid phases and thus it possesses orientational/positional orders as a crystalline solid and fluidity as a liquid. LCs exhibit a number of physical properties, including large physical anisotropies high susceptibility to external stimuli, and thus they are oftentimes the best material for applications ranging from displays to sensors and photonic circuits. Traditional rod-like nematic LCs with large physical anisotropies enables superior light modulation such as optical phase, intensity, and polarization, and other special kinds of LCs (e.g., cholesteric, blue phases), exhibiting unique helical structures or electro-optic properties have potential for manipulating light spectrally and/or temporally and generating lasers. Many LC based tunable devices have been developed, including tunable lasers, multi-stable optical switches, and diffractive optical elements. In addition, LCs have been introduced into passive silicon photonics devices for realizing active silicon photonics devices.
