Characterization of Hexagonal Photonic Crystal Fiber for Zero Flattened Dispersion with Lower Confinement Loss and Residual Dispersion Compensation Over 500 nm Wavelength Bandwidth

Abstract

Design methodology and characteristics analysis of a hexagonal photonic crystal fiber (H-PCF) is presented in this paper. Here, chromatic dispersion, effective area and confinement loss are analyzed for 1.00 to 2.10 μm wavelength range. The PCF is simulated by finite element method (FEM) with perfectly matched layers (PML). Hexagonal PCF with five rings of air holes for near zero ultra-flattened dispersion over 1100 to 1600 nm wavelength range is shown. The special property of proposed PCF is the design simplicity with near zero ultra-flattened dispersion, which is much needed in wavelength division multiplexing (WDM) applications. According to simulation work it is shown that, the designed microstructure optical fiber (MOF) shows near zero ultra-flattened dispersion of 0±1.00 ps/(nm.km), nonlinearity of 12.15 W -1 km -1 and confinement loss less than 10 -2 dB/km at the operating wavelength of 1550 nm.
