Two Sides Rhombus Shaped Cladding Hexagonal PCF with Low Confinement Loss and Negative Dispersion

A novel design of solid core photonic crystal fiber (PCF) has been proposed with seven rings rhombus inside eight rings hexagonal structure. Waveguide properties have been numerically investigated by utilizing the full vectorial finite element method (FEM). Here the paper elaborates PCF characteristic like confinement loss, dispersion properties, normalize frequency, mode field diameter, effective area, and nonlinear coefficient with asymmetric cladding designed and investigated. Silica is used as background material. The calculated value shows the ultra-low confinement loss in 1.1 µm to 1.7 µm, low negative dispersion -400ps/km-nm achieved in solid core. The high nonlinear coefficient 3.1661762 W-1km-1 and 3.141089 W-1km-1 at 1.55 µm in xpolarization and y-polarization mode respectively achieved. PCF achieved low confinement loss and better mode field diameter for remote sensing application.
