Abstract

This work proposes a new approach to the design of hollow-core fiber for single-polarization application. The hollow-core fiber has a cladding with high air filling fraction consisted of hexagonal air-holes in a hexagonal lattice. The novelty design consists of changing the diameter of just one radial line of air-holes. The asymmetric cladding leads to obtain fundamental core modes with high birefringence, and fundamental modes with transmission bandgaps in different spectral range. The shift in the bandgaps results in a high polarization dispersion loss (PDL > 20dB/m) with bandwidth of about 38 nm. At the wavelength 1500 nm the PDL is about 3000 dB/m and the confinement loss to the guided mode is about just 0.1 dB/km.
