Mid-infrared high birefringence bow-tie-type Ge20Sb15Se65based PCF with large nonlinearity by using hexagonal elliptical air hole

An elliptical core-based D-shape photonic crystal fiber (PCF) has been proposed with achieving extraordinary optical properties in this paper. We deeply observed and evaluated the performance of the designed D-PCF by doping the materials (As 2 S 3 and As 2 S 5 ) separately into the core region with the variation of the eccentricities (core size). After the whole analysis, this D-PCF prefers the As 2 S 3 core material because it produces a better performance of all the optical features compared to the As 2 S 5 material. The results of the raised PCF shows that the maximum nonlinearity of 9.114×10 4 W −1 km −1 , the extreme-high birefringence of 0.254, the better power fraction of 99.51%, the high numerical aperture of 0.78, the large negative dispersion of −2560.12 ps/(nm-km), and the low beat length of 7.09 μm, etc. The finite element method (FEM) has been applied to simulate the optical characteristics and a perfectly matched layer (PML) is used as a boundary condition. So, the above mentioned remarkable outcomes of the designed D-PCF makes it a robust candidate in many helpful applications like biomedical imaging, telecom, super-continuum generation, and polarization-maintaining signal processing.

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 μm 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.
