Over the last decade, intense interest in both basic science and industry has been generated by the physics and uses of fiber-based supercontinuum (SCG) sources. Here, we present our findings about the design and characterization of PCFs based on Tellurite, which combines the following benefits: high nonlinearity, high Birefringence (BR), formation of supercontinuum, coherent normal dispersion ... [Show full abstract] profile, and optical range transmission potential with flattened chromatic dispersion profile equal 0.5327 ps/nm km up to a wavelength of around 1.65 μm. Optical properties such as Birefringence, confinement losses (CL), effective refractive index (Neff) and effective mode area (Aeff) are comprehensively examined and explored using the Finite element method (FEM) while employing the solution of nonlinear Schrödinger equations (GNLSE) to profile the temporal and spectral wave propagation. The simulation results show that zero-dispersion is achieved in the proposed PCF design at 1.5 to 1.65 μm. The chosen fiber topology can produce a large supercontinuum spectrum from approximately (1200–2000) nm covering S–C–L bands. The designed PCF will be a good fit for various applications, including biophotonics, Spectroscopy, biosensing, biomedical imaging, and ultra-broadband signal amplification.
