“…Even though HC-PBG fibers have already been produced with elliptical core, either placing the preform off-center in the furnace during drawing [12] or with a 4-cells core [13], it is the first time to our knowledge that a pressure control of some of the cladding holes is used to induce an ellipticity to the core.…”

“…The fiber in Fig.6 without cladding defects has a minimum loss of ∼ 20dB/km. Fiber III has a [12], that has similar polarization properties, an aspect ratio of 1.4 and a minimum loss of ∼ 100dB/km, would suggest that the elliptical core is responsible to the increased loss. Nevertheless a weak coupling between the fundamental mode and the cladding defect modes can not be completely excluded.…”

A novel single-polarization single-mode hollow-core photonic bandgap fiber with thin slab waveguide (TSW) was designed and simulated. Single-polarization guidance is achieved by the high loss of a polarized fundamental mode (FM) induced by mode coupling with a higher-order TE/TM mode of TSW and low loss of another polarized FM. We achieve a polarization loss ratio ∼ 46.9 dB, birefringence Δn ∼ 2.4 × 10−4, loss ∼ 35.9 dB/km and minimum higher-order mode extinction ratio > 15 dB. Moreover, the performance could be maintained when the guidance wavelength λ = 1.44 ∼ 1.56 µm and bending radius rc > 9 mm. The proposed model will be suitable for application as resonator sensing paths of miniaturized resonator fiber optic gyroscopes, high-performance interferometers, fiber lasers, frequency metrology, quantum communications, and laser-based gas sensing, etc.
