• Photonic crystal fiber
• Triangular lattice structure
• Ultra-flattened negative chromatic dispersion
• Residual dispersion compensation

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 (Delta D) of -(253.5 +/- 2.5) and -(292 +/- 2) ps/nm/km respectively for both X and Y polarization modes within the wavelength boundary of 1.254 <- 1.7 mu m (450-nm band). Moreover, +/- 10% alteration in the optimum parameters (OP) is also studied to assess the responsiveness of the dispersion characteristics.
