Development of a liquid crystal optical resonator coupled with optical confinement of a hollow fiber

胆甾型液晶具有自组装形成的螺旋结构，由于其螺旋结构可以看作是一维的准光子晶体，近年来引起了人们的广泛关注。在本研究中，研究了胆甾相液晶在光学中空光纤中的光学限制。胆甾相液晶具有一维取向，在中空纤维中是二维取向的。这表明，中空纤维结构能够为胆甾相液晶创造更高的有序结构。

Cholesteric liquid crystals, which have a helical structure formed by self-assembly, have recently attracted much attention because their helical structure can be regarded as a one-dimensional pseudo-photonic crystal. In this research, the optical confinement of a cholesteric liquid crystal in an optical hollow fiber is investigated. The cholesteric liquid crystal, which has a one-dimensional orientation, is oriented in two-dimension in the hollow fiber. This indicates that the hollow fiber structure enables to create a higher order structure for cholesteric liquid crystals.
