Dispersion Compensating Photonic Crystal Fiber with Enhanced Properties Achieved by Modified Core Geometry

Abstract

A novel dispersion compensating fiber based on photonic crystal fiber has been designed and studied in terms of optimal dispersion and operating bandwidth. The investigation of dispersion characteristics with respect to change in hole diameter and pitch has been provided. Further optimization of the designed fiber has been applied to the achieved fiber’s properties in order to achieve a potentially easy-to-fabricate dispersion compensating fiber.
