Hybrid hollow-core polarization-maintaining fiber with high birefringence and wide single mode bandwidth

Results in Physics, 2021
A novel hybrid hollow-core polarization-maintaining fiber is proposed by combining the photonic bandgap mechanism and anti-resonant effect. High birefringence can be achieved by introducing a pair of negative curvature anti-resonant layers into the air ...

High birefringence single-polarization composite structured anti-resonant fiber

Results in Physics, 2023
We propose a highly birefringent, single-polarization composite structured anti-resonant fiber (CS-ARF). The proposed CS-ARF has an elliptical core, two symmetrically spaced arrays of elliptical air holes, and a six-tube anti-resonant structure.
