Abstract
A novel design of circular hybrid photonic crystal fiber (CH-PCF) with high nonlinearity and high numerical aperture (NA) is introduced in this paper. The numerical simulation results are obtained by using finite element method (FEM) and selecting finer mesh. Some fundamental optical parameters such as nonlinearity, effective area, scattering loss, power fraction and NA for the two orthogonal polarized modes are rigorously evaluated. Significant improvement of PCFs in terms of the non-linearity and NA are demonstrated by carefully investigating of the geometrical parameters of structure. The reported design undoubtedly confirms high nonlinearity of 128873.1183â¯Wâ1kmâ1 for x-polarization and 152134.1052â¯Wâ1â¯kmâ1 for y-polarization respectively at the optical wavelength of 0.5â¯Î¼m. Simultaneously, outmost NA of 0.57 and 0.59 are found at optical wavelength λâ¯=â¯2.5â¯Î¼m. So, the obtained outcomes make the proposed PCF a prominent candidate in super continuum generation as well as all optical signal processing applications.
