Research on Dispersion Compensating Property and Nonlinear Coefficient of Photonic Crystal Fiber

Abstract

A full-vector effective refractive index model is used to analyze the influence of the nonlinear coefficient and dispersion property on the structural parameters of photonic crystal fiber (PCF). It is possible to design dispersion compensating PCF flexibly with high dispersion value, negative dispersion slope and lower nonlinear coefficient around 1550 nm. Simulation and analysis show that highly nonlinear PCF provides great potential value as dispersion compensation fiber.
