Analysis of Dispersion and Nonlinear Property in Doping Defected Core Spiral Photonic Crystal Fiber
Journal Title: Current Journal of Applied Science and Technology - Year 2017, Vol 19, Issue 2
Abstract
We propose a novel nearly zero-dispersion fiber (NZDF) at the operating wavelength based on GeO2 doped SiO2 square defected core spiral photonic crystal fiber (dd-SPCF). The 2-D finite element method with perfectly matched layer boundary condition is introduced to investigate the guiding properties using COMSOL Multiphysics 4.2.0.150. The angular displacement and diameter of circular air holes of spiral arms in the designed dd-SPCF have been tuned to offer near zero dispersion as well as low effective area. The proposed dd-SPCF shows promising dispersion characteristics (-0.000169 ps/km-nm) with very low effective area (2.6516 ) and high nonlinear 76.44 parameter at operating wavelength 1.55 μm, making it a suitable candidate for chromatic dispersion controller and nonlinear optical applications.
