Liquid Sensing of Hexagonal Photonic Crystal Fibers for Terahertz Wave
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.
