Lotus shaped negative curvature hollow core fibre with 10.5 dB/km at 1550 nm wavelength

摘要

We present a novel negative curvature antiresonant hollow core fibre design with the potential for low loss and very wide bandwidth. A low loss of 10.5 dB/km at 1550 nm is demonstrated, showing its potential for use in data transmission and high power beam delivery applications.
