Abstract

This paper presents a design of hollow-core bandgap fiber operating as single-polarization single-mode device. The hollow-core fiber has a cladding with high air filling fraction consisted of hexagonal air-holes in a triangular lattice. The design consists of changing the diameter of one radial line of air-holes. The asymmetric cladding leads to obtain single-mode operation with high birefringence, and fundamental modes with bandgaps in different spectral ranges. The single-polarization single-mode condition is demonstrated over 11 nm with polarization dispersion loss (PDL) of 800 dB/m at 1550 nm. The birefringent and polarizing hollow-core fiber is proposed to fiber optic gyroscope (FOG) applications.
