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

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR
spectrum, which is becoming increasingly more prominent in a variety of scientific …

For over 50 years, pure or doped silica glass optical fibres have been an unrivalled platform
for the transmission of laser light and optical data at wavelengths from the visible to the near …

We investigate hollow-core fibers for fiber delivery of high power ultrashort laser pulses. We
use numerical techniques to design an anti-resonant hollow-core fiber having one layer of …

Mid-infrared (IR) lasers are currently an area of rapid development, with several competing
technologies. In traditional gas lasers, the effective interaction length is limited and the …

We first use numerical simulations to show that bending losses of hollow antiresonant fibers
are a strong function of their geometrical structure. We then demonstrate this by fabricating a …

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 …

We report on damage-free fiber-guidance of milli-Joule energy-level and 600-femtosecond
laser pulses into hypocycloid core-contour Kagome hollow-core photonic crystal fibers. Up …

Simple structures are always a pursuit but sometimes not easily attainable. It took
researchers nearly two decades for conceiving the structure of single-ring hollow-core …
