Design and numerical analysis of a photonic crystal fiber (PCF)-based flattened dispersion THz waveguide

Design and analysis of low loss solid-core hexagonal photonic crystal fiber for applications in terahertz regime

“…Introduction Photonic Crystal Fiber (PCF) has the capability to localize and guide light as these structures exploit excellent optical properties which are not possible using conventional optical fibers. In recent years, PCFs have drawn significant consideration due to certain unique characteristics like endless single mode [1], large effective mode area [2], high birefringence [3], high nonlinearity [4] and tunable dispersion [5] compared to the conventional fibers. The popularity of PCF is due to its lower weight, high flexibility and low loss in optical signal [6].…”
