We review and compare recent hollow core photonic crystal fibers, both bandgap-guiding and anti-resonant, which were designed and fabricated for high power laser delivery applications.
The first multi-terabit/s WDM data transmission through anti-resonant hollow-core fiber is demonstrated. 16×32-GBd dual-polarization Nyquist-shaped 256QAM channels propagated through a 270-m long fiber. No non-linearity penalty was observed for powers up to 1W.
• Various different classes of fiber (capillary, ARF and PBGF) each with relative merits and drawbacks for specific applications • Significant progress made over recent years in the development of HCF technology — both in terms of understanding and fabrication • Increasing array of applications, with some e.g. power delivery and high power wavelength conversion, close to commercial deployment • Current...
We report a low loss (∼12.3dB/km), 37-cell hollow-core photonic bandgap fiber operating in the 1μm spectral region and demonstrate its bend-insensitive operation and its use for high power laser beam delivery.
We review recent progress in the development of hollow core optical fibres for telecoms/datacoms, highlighting in particular their suitability for low-latency/time-sensitive applications, and their ultimate potential for broadband, ultralow loss (and nonlinearity) transmission.
We demonstrate a hollow-core photonic bandgap fiber delay-line based 10 GHz Optoelectronic oscillator (OEO) with over 6 times less temperature induced frequency drift compared to a standard single mode fiber delay-line based OEO.
We report an effectively singlemode tubular antiresonant hollow core fiber with >1000nm bandwidth and record-low loss of 25dB/km, fully connectorizable with SMF28. We demonstrate penalty-free data transmission at wavelengths of 1065, 1565 and 1963nm.
We discuss our recent progress in hollow core-photonic bandgap fiber fabrication for high capacity transmission, focusing on two key areas: longitudinal uniformity and length upscaling as well as reviewing highlight results in data transmission.
We review our recent work on the modelling, fabrication and characterization of hollow-core photonic bandgap fibers. We discuss the modal content of these fibers, as well as the opportunities and challenges presented by modal interactions in space division multiplexed transmission applications.
We have examined the interaction of the antimicrobial peptide indolicidin (IND) with large unilamellar vesicles of the zwitterionic phospholipid 1-palmitoyl- 2-oleoyl phosphatidylcholine (POPC) and of 2:1 mixtures of POPC and negatively charged 1-palmitoyl-2-oleoyl phosphatidylglycerol (POPG). We also investigated the interaction between IND and lysophosphatidylcholine (LPC) and LPC–lysophosphatidylglycerol...

We thoroughly study possible ways to introduce high birefringence and differential loss in hollow core anti-resonant fibres. We present the design of realistically achievable fibres with large birefringence and effectively polarising behaviour over the entire C-band.
Two powerful simulation tools are combined to predict geometry and optical properties of Hollow Core Photonic Band Gap fibres from their preform structure and draw parameters. Broad parameter space scans allow identifying structures for optimal optical performance.
We present for the first time the group velocity dispersion of multiple distinguishable modes propagating in 3, 7 and 19 cell hollow core photonic bandgap fibres. Measurements are made by direct phase extraction from spectral domain low coherence interferometry.
4×10Gbps WDM transmission over low loss HC-PBGF at 2μm wavelengths is demonstrated using a 2mm long QCSE based InP MZM with Vπ of 6V and ER>20dB. An OSNR of 25dB is required to achieve error free transmission.
We demonstrate a longitudinally resolved Optical Side Scattering Radiometry (OSSR) technique to measure discrete and distributed scattering loss with >60dB dynamic range and 5cm spatial resolution. We apply it to a record-length 11km hollow core photonic band-gap fibre.
We review progress in the design, fabrication and characterisation of hollow core photonic band gap fibres that have led to the production of low-latency data transmission fibres of >10 km length with 200nm bandwidth and losses at the 5dB/km level.
We analyze defect-induced mode coupling in a hollow-core photonic bandgap fiber using time-of-flight, and show its utility in complementing optical time-domain reflectometry.
