Optimum Design of a Nearly Zero Ultra-flattened Dispersion with lower Confinement loss Photonic Crystal Fibers for Communication Systems

Abstract

This paper presents a triangular-lattice photonic crystal fiber for analysis of nearly zero ultra-flattened dispersion like 0.96 - -0.86 ps/nm/km with very low confinement loss less than 10 -5 db/km, moderate effective area, lower splice loss & nonlinear coefficient property of photonic crystal fibers. A five-ringed photonic crystal fiber have be designed using Comsol 4.2 with the finite element method and perfectly matched absorbing layers boundary condition is used to investigate the guiding properties .
