摘要

设计了一种分别填充水、酒精和苯炔等边三角形空气孔纤芯、包层空气孔排列为正六边形结构、以环烯烃共聚物作为基底材料的光子晶体光纤，利用有限元法模拟了0.3~1.5 THz频带内的液体传感特性。结果表明，设计的光子晶体光纤的灵敏度系数很高，当纤芯空气孔直径

=2.4 m、包层空气填充比为0.3时，苯炔在频率0.3 THz的相对灵敏性系数最高为37.63%，在1.5 THz，限制损耗的数量级可以降至10

Abstract

A photonic crystal fiber with the cladding of circular air holes in hexagonal lattice structure and the core of circular air holes in equilateral triangle lattice structure based on cyclic-olefin copolymer is proposed

the liquid sensing characteristics of the PCF over 0.3-1.5 THz bands are investigated by finite element method. The proposed PCF demonstrates an ultrahigh sensitivity coefficient of 37.63% at 0.3 THz

and the confinement loss is low as the order 10 at frequency of 1.5 THz. The results offer reference for designing novel liquid sensors based on PCF at terahertz band.
