Abstract

This paper presents a novel structure of photonic crystal fiber (PCF). Using the finite element method, a new type of LC PCF terahertz waveguide by voltage modulation is designed which is based on that the holes of PCF filled with nematic LC 5CB. We use COMSOL and MATLAB to simulate and calculate the parameters of PCF of different structures under THz wave band. We made PCF have continuously tunable sensing properties without changing its structure. It provides great convenience for the practical application..
