Abstract

Abstract: This study proposes two tellurite-based PCFs whose are OSOC-PCF (Octa-Spiral with Octagonal Cladding PCF) and DSHC-PCF (Dodeca-Spiral with Hexagonal Cladding PCF) designs with higher nonlinearity and higher birefringence. Result comparisons of proposed PCFs are mentioned and demonstrated in this research study. By applying the finite element method with the assistance of COMSOL Multiphysics, we have investigated and simulated guiding properties like nonlinear coefficient, birefringence, dispersion, bending effect, confinement loss, power fraction, effective material loss. Comparing both designs, the highest nonlinearity is gained by OSOC-PCF reaches up to 7333 W −1 Km −1 around 1.55 μ m of wavelength and obtained birefringence of 5.85 × 10 −2 wherein, a slight confinement loss occurs. The alluded PCFs possess an upstanding structure that associates operating an easy fabrication process. The convenience of propounded PCFs has plenty of purposes in polarization maintenance, optical communication, faster data communication, and super-continuum generation.
