We describe the history, guiding mechanism, recent advances, applications, and future
prospects for hollow-core negative curvature fibers. We first review one-dimensional slab …

Since their inception, about 20 years ago, hollow-core photonic crystal fiber and its gas-filled
form are now establishing themselves both as a platform in advancing our knowledge on …

Over the past few years, progress in hollow-core optical fiber technology has reduced the
attenuation of these fibers to levels comparable to those of all-solid silica-core single-mode …

Countering the optical network 'capacity crunch'calls for a radical development in optical
fibres that could simultaneously minimize nonlinearity penalties, chromatic dispersion and …

High-performance interferometers, gyroscopes, frequency combs, quantum information
experiments and optical clocks rely on the transmission of light beams with the highest …

In attosecond and strong-field physics, the acquisition of data in an acceptable time
demands the combination of high peak power with high average power. We report a 21 W …

In the research field of hollow-core optical fiber (HCF), one type of fiber geometry with a
leaky mode nature has unexpectedly taken center stage over the last couple of years: the so …

Chalcogenide hollow-core anti-resonant fibers (HC-ARFs) are a promising propagation
medium for high-power mid-infrared (3-5? µm) laser delivery, while their properties have not …

Remarkable recent demonstrations of ultra-low-loss inhibited-coupling (IC) hollow-core
photonic-crystal fibres (HCPCFs) established them as serious candidates for next …

We report an effectively single mode tubular antiresonant hollow core fiber with minimum
loss of∼ 25 dB/km at∼ 1200 nm, and an extremely wide low-loss transmission window …
