摘要

The research investigates the impact of birefringence loss in quartz-based mid-infrared photonic waveguides over various wavelength ranges. The analysis of three specified wavelength ranges from 1 to 12 µm assesses critical optical parameters such as effective index, loss, group index, TE polarization percentage, and effective area. Polarizing balancing results in increased losses in modes with reduced TE polarization fractions, hence significantly diminishing the scattering loss rates. By employing suitable area modifications, one can enhance mode confinement and hence mitigate loss escalation induced by the magnetic field. Field dispersion is affected by birefringence phenomena about the appropriate area size. The waveguides exhibit low dispersion and minimal pulse broadening while maintaining a nearly uniform group index across all supported modes. Quartz-based waveguides are suitable for optical communication, sensing applications, and spectroscopic solutions, operating within a wavelength range of 1.55–3 µm. The numerical simulation of optical properties is conducted to ensure precise evaluation of waveguide performance.
