Description
Summary:In this paper, novel spiral-shaped photonic crystal fiber (S-PCF) is proposed in the near-infrared regime up to 2600 nm of operating wavelength. With that features, silica (SiO 2 ) background of S-PCF is doped with gold (Au) and silver (Ag) nanoparticle and the elliptical core region is formed by comprising silicon rod. This nanocomposited S-PCF is then optimized well for spiral arm whose radius at each layer is varied from 1000 to 350 nm and the radius of core region is fixed as 600 nm. Using finite element method (FEM), different optical properties such as effective index, birefringence, dispersion, effective area, nonlinearity, and power fraction ratio are numerically investigated for different cases of PCF such as undoped silica substrate, Ag-doped silica substrate, and Au-doped silica substrate. The simulation results are obtained and inferred that the nanoparticle-doped PCF is promising for the better performance in the near-infrared region than the case of undoped S-PCF.
