TL;DR: Using hollow-core NANFs with 5-nested-tubes, this work achieves the lowest loss ever reported in a hollow core fiber at 1300 and 1625nm and in any type of optical fiber at 850nm and 1060nm.

Designing multi-mode anti-resonant hollow-core fibers for industrial laser power delivery.
TL;DR: In this paper , the design of hollow-core fibers for the delivery of 10s of kilowatt average power from multi-mode laser sources is investigated, and numerical simulations indicate that optimized fibers could in principle deliver nanosecond pulses with greater than 100 mJ pulse energy over distances up to 1 km.

- 08 Mar 2020
TL;DR: This work presents antiresonant hollow-core optical fibre designs for VCSEL-based short-reach transmission applications in the 850nm band and shows that lower loss and twice the bandwidth of solid, multi-mode, graded index fibres are possible.

TL;DR: In this paper , the authors present recent developments in Nested Anti-resonant Nodeless Fiber (NANF) design over the last few years and show how this rapidly developing technology has been refined to produce state-of-the-art HCFs at wavelengths between 850 − 1625 nm.
