Abstract
Analysis of numerical design and properties of a new silica based photonic crystal fiber (PCF) are proposed in this manuscript. The design performs ultra-flattened negative chromatic dispersion (UNCD) in the optical windows 2nd and 3rd involving O to U bands in the infrared (IF) portion. The guiding properties are observed by employing a circular perfectly matched layer (PML) boundary through the finite-element method (FEM). The proposed design is compatible for the application of residual dispersion compensation (RDC) as it grants negative dispersion (ND) and very low scale dispersion variation (ΔD) of −(253.5±2.5) and −(292±2) ps/nm/km respectively for both X and Y polarization modes within the wavelength boundary of 1.25⟷to1.7 μm (450-nm band). Moreover, ±10% alteration in the optimum parameters (OP) is also studied to assess the responsiveness of the dispersion characteristics.
