We demonstrate analogue photonics links using hollow-core fibres, showing they significantly surpass the performance of standard fibre analogue links in every metrics of link gain, noise figure, and dynamic range.

Light guidance in air has significant potential in diverse photonics applications, one of hich is optical communications where it may be key to achieving lower attenuation and optical nonlinearity than in conventional silica fibres. This thesis prese

Abstract We demonstrate halving the record-low loss of interconnection between a nested antiresonant nodeless type hollow-core fiber (NANF) and standard single-mode fiber (SMF). The achieved interconnection loss of 0.15 dB is only 0.07 dB above the t

Hollow core fibers have low light attenuation because the light travels through air rather than glass, but other sources of loss have limited the performance so far. Here the authors design and demonstrate a Nested Antiresonant Nodeless hollow core f

We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with g

Positioning accuracy in 5G networks (achieved via techniques based on observed time difference of arrival (OTDoA)) is limited by the synchronization error between the cellular base stations. Here, we demonstrate that these base stations can be synchr
