High birefringence, single-polarization, low loss hollow-core anti-resonant fibers.
Optics Express, 2021 We present a novel hollow-core anti-resonant fiber (HC-ARF) with a cladding ring, two nested resonant tubes and two nested silicon tubes. The cladding ring in the fiber contributes to decrease the fundamental mode (FM) loss of x-polarization and enlarge ...
