Abstract
A newly developed pentagonal photonic crystal fiber (P-PCF) with high nonlinearity and birefringence has been introduced in this work. Numerical analysis is carried out across the broader wavelength spectrum from 1.0 to 2.0 mu m within the inferred region (IR). Furthermore, using the finite element method (FEM) with smaller mesh, a numerical examination of several optical characteristics such as effective mode area (EMA), nonlinearity, numerical aperture (NA), birefringence, and V-parameter was carried out. By using a circular completely matched layer (PML), the proposed P-PCF's optical transmission qualities have been guided. For the x-polarization mode, the suggested P-PCF exhibits high nonlinearity of 1.6 x 10(4) W-1 Km(-1) at the working wavelength of lambda = 1.4 mu m. Furthermore, the proposed structure offers strengthening birefringence 2.5 x 10(-6) at 1.6 mu m wavelength including numerical aperture (NA) of 0.44 for the X-polarization mode. Based on the outstanding advantages, it can be asserted that the suggested model will find a promising domain of application in the area of all optical signal processing, sensing applications, and coherent optical communications.
