Hybrid-cladding hexagonal-core photonic crystal fiber: A platform for ultra-sensitive terahertz detection of industrial liquid

In this work, a hexagonal-core photonic crystal fiber (PCF) with hybrid rectangular and triangular cladding air holes for extremely sensitive chemical detection in the terahertz regime is proposed and numerically investigated. The finite element technique (FEM) in COMSOL Multiphysics is used to mode...
