Measurement of Confinement loss and Dispersion of Holey Fiber having Elliptical Shape of Holes

In this paper, we design a novel Hexagonal Lattice photonic crystal fiber (PCF) made of soft glass achieving low confinement loss and low chromatic dispersion through the optimization of the arrangement and diameter of elliptical shape of air holes. The motivation behind this is to optimize the design parameter of PCF to gain low-flattened chromatic dispersion and low confinement loss at wide wavelength range. This new design of PCF having low-flattened chromatic dispersion and low confinement loss in wide wavelength range is demonstrated by carefully adjusting the air holes in each rings, air holes dimensions and spacing between air holes or pitch. 2-D finite difference time domain (FDTD) method is used for the analysis of this PCF
