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 …

Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air
holes that run along the entire fiber length. Largely through their ability to overcome the …

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 …

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 …

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

We propose a novel hollow core fiber design based on nested and non-touching
antiresonant tube elements arranged around a central core. We demonstrate through …

Attenuation in photonic bandgap guiding hollow-core photonic crystal fiber (HC-PCF) has
not beaten the fundamental silica Rayleigh scattering limit (SRSL) of conventional step …

A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …

We report the fabrication of a new type of optical waveguide: the photonic crystal fiber. It
consists of a pure silica core surrounded by a silica–air photonic crystal material with a …

We made an all-silica optical fiber by embedding a central core in a two-dimensional
photonic crystal with a micrometer-spaced hexagonal array of air holes. An effective-index …
