Abstract:
A novel single material-based anti-resonant fiber is designed, investigated, and explored
in this article with supports of up to 64 OAM modes over the 0.6 lm to 1.0 lm as operating wavelength. The other properties of the designed fiber including confinement loss (CL), OAM purity,
effective refractive index differences (ERIDs), and dispersion variations provide the exceptional
output. This fiber, the CL approximately varies between the 5.7031 105 dB/m to
9.2537 104 dB/m, the OAM purity is 97% to 99%, the ERIDs are higher than 104 for all
the modes, and the least dispersion variations is 8.838 ps/km-nm for the EH1,1 mode. All the outstanding properties of the presented fiber are calculated using the FEM and the PML within the
COMSOL Multiphysics simulator. Therefore, to the ideal of our knowledge, the proposed antiresonant fiber is mostly applicable in the high-quality long-distance fiber communications system.
