Optimization of a Hybrid Core Photonic Crystal Fiber for THz Applications

saikat ray, mohammad mohiuddin uzzal


Despite several real-life applications, the development of low-loss terahertz waveguide is still a challenge for long-distance applications due to its low confinement and high propagation loss. In this paper, an octagonal waveguide structure has been optimized for minimum propagation loss in the THz frequency band. The optimized structure has a core diameter of 300 um with an operating frequency of 1.1 THz. From the optimized structure, we found optimized power confinement having core power fraction of 53%.
