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 …

In this review, we introduce photonic crystal fibre as a novel optofluidic microdevice that can
be employed as both a versatile chemical sensor and a highly efficient microreactor. We …

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 …

Over the past decade intense laser fields with a single-cycle duration and even shorter,
subcycle multicolour field transients have been generated and applied to drive attosecond …

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

We present a semiconductor saturable absorber mirror (SESAM) mode-locked thin-disk
laser generating 80 μJ of pulse energy without additional amplification. This laser oscillator …

We report on numerical and experimental studies showing the influence of arc curvature on
the confinement loss in hypocycloid-core Kagome hollow-core photonic crystal fiber. The …

Revolver optical fibers (RF) are special type of hollow-core optical fibers with negative
curvature of the core-cladding boundary and with cladding that is formed by a one ring layer …

In this paper, we report the use of a 3-meter low-loss anti-resonant hollow-core fiber (AR-
HCF) to deliver up to 300 W continuous-wave laser power at 1080 nm wavelength from a …
