Abstract

We present a novel Lotus shaped negative curvature antiresonant hollow core fiber with the potential for low loss and very wide bandwidth. A minimum loss of ~10 dB/km at 1550 nm and less than 100 dB/km over a bandwidth of ~650 nm is demonstrated, with effectively single mode behaviour over lengths of a few tens of meters. We demonstrate power penalty free 10.5-Gbit/s data transmission through an 86 m length of fiber at both O and C telecom bands. The fiber macro bend sensitivity has also been tested, which is relevant for telecom as well as for other applications including beam delivery and gas based sensing. The bend loss is found to be below 0.2 dB/m for bend radii down to 8 cm at wavelengths away from the short wavelength edge of the transmission band.
