Bound states in the continuum (BICs) are waves that remain localized even though they
coexist with a continuous spectrum of radiating waves that can carry energy away. Their very …

Quantum mechanics is an extremely successful theory that agrees with every experimental
test. However, the principle of linear superposition, a central tenet of the theory, apparently …

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 …

High-power laser delivery with near-diffraction-limited beam quality is typically limited to tens
of metres distances by nonlinearity-induced spectral broadening inside the glass core of …

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 …

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 …

Photonic crystal fibres have wavelength-scale morphological microstructure running down
their length. This structure enables light to be controlled within the fibre in ways not …

For a physicist, and more generally for a scientist, one of the pleasures in everyday life is to
detect exemplifying manifestations and avatars of the topic he is working on. Why do small …

We review the use of hollow-core photonic crystal fibers (PCFs) in the field of ultrafast gas-
based nonlinear optics, including recent experiments, numerical modeling, and a discussion …
