Design and Analysis of Graded Rectangular-Core Photonic Crystal Fiber for Terahertz Communication

摘要

Photonic Crystal Fibers have proved to be an efficient medium for propagation of electromagnetic radiation especially in the Terahertz regime. Located between the infra-red and microwave region, the Terahertz frequency range lies within 0.1 to 1 Terahertz. We report a design of a graduating ring rectangular-core Photonic Crystal Fiber, having background material as Cyclic-Olelin Copolymer (COC), with extremely low confinement loss of 4.9399× 10~(-7) dB/cm and material loss of 0.2 cm~(-1) at 0.22 mm pitch value. Due to the very low loss values, such a structure of the Photonic Crystal Fiber can be used for efficient low-loss data communication.
