“…For multiple layer structure, each layer is also considered as an individual Fabry-Perot resonator, and the leakage is well-controlled to be lower than the one obtained from a single cladding layer. In general, the leakage loss is maximized at the resonance wavelength which can be expressed as [23,24]…”

A polarization-maintaining and polarization-filtering hollow core fiber with nested anti-resonant nodeless tubes for the THz regime is proposed. The model is designed by the finite element method to operate at 1.0 THz using TOPAS copolymer as the fiber material. The proposed structure consists of four outer tubes with one inner tube each in the orthogonal arrangement. The fiber was optimized to obtain the lowest loss by varying the tube thickness. The simulation results show that the thickness of 0.09 mm was suitable for a low loss of 0.2 dB/m operating at 1.0 THz. The fiber property of high birefringence @ 1.5x10-4 was made by introducing unequal radial distances between the outer and inner tubes of the orthogonal arrangement. In addition, at a particular difference of the radial distance, it was found that the proposed fiber can act as a polarization filter indicating by having a high crosstalk.

Fibers with high birefringence and low loss offer notable benefits in the areas of sensing, communication, and polarization filtering. An asymmetry subwavelength suspended-core terahertz (THz) fiber composed of rectangular and arc-shaped dielectric layers is studied. Simulation results show that the fiber has both ultra-high birefringence and low loss characteristics. The birefringence value is higher than 0.038 from 0.8 to 1.0 THz, and the transmission losses of two polarization modes are lower than 0.5247 dB∕cm when the thicknesses of all dielectric layers are the same. We note that the birefringence value can be further increased by adjusting the thickness of the rectangular dielectric layer. The birefringence value reaches the order of 10 −1 in the frequency range of 0.82 to 1.98 THz. At 0.82 THz, the losses for x -and y -polarization modes are 0.3705 and 0.0754 dB∕cm, respectively. Therefore, this type of fiber will be of great significance in eliminating the adverse influences of polarization effects in THz systems.
