利用光诱导调制的方法，将预聚物/液晶溶液渗透到固体核光子晶体光纤（PCF）的空心通道中，制备了基于聚合物/液晶的光纤布拉格光栅（PLC-FBG）。讨论了光子带隙引导进入渗透PCF的制备工艺和相关影响，以及PLC-FBG的表征。本文给出的实验数据表明，PLC-FBG的液晶内含物导致了高的热灵敏度和弯曲灵敏度。利用扫描电子显微镜研究了聚合物/液晶相在PCF毛细管内分离的微观行为，并进行了进一步的讨论。
A polymer/liquid crystal-based fiber Bragg grating (PLC-FBG) is fabricated with visible two-beam holography by photo-induced modulation of a prepolymer/liquid crystal solution infiltrated into the hollow channels of a solid core photonic crystal fiber (PCF). The fabrication process and effects related to the photonic bandgap guidance into the infiltrated PCF, and characterization of the PLC-FBG, are discussed. Experimental data presented here demonstrate that the liquid crystal inclusions of the PLC-FBG lead to high thermal and bending sensitivities. The microscopic behavior of the polymer/liquid crystal phase separation inside the PCF capillaries is examined using scanning electron microscopy, and is discussed further.
