Analysis of Microstructured Photonic Crystal Fiber: An Improved Design

A single-mode defected core hexagonal photonic crystal fiber (H-PCF) is presented for the wide-band dispersion compensation at the wavelength interval 1350 to 1600 nm over the telecommunication windows. Finite element method (FEM) is incorporate to investigate the characteristics of the proposed PCF. Throughout the simulation, we found dispersion of −2160 ps.nm

at the operating wavelength of 1550 nm. Our proposed paper enhances its attraction for using single circular hole of air in the core site which is the most suitable one for the optical fiber communication systems.
