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 …

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 …

This article offers an extensive survey of results obtained using hybrid photonic-crystal fibers
(PCFs) which constitute one of the most active research fields in contemporary fiber optics …

The physics and applications of fiber-based supercontinuum (SC) sources have been a
subject of intense interest over the last decade, with significant impact on both basic science …

Supercontinuum (SC) generation based on ultrashort pulse compression constitutes one of
the most promising technologies towards ultra-wide bandwidth, high-brightness, and …

We report broadband all-fiber optical phase modulation based on the photo-thermal effect in
a gas-filled hollow-core fiber. The phase modulation dynamics are studied by multi-physics …

Infrared femtosecond laser pulses are important tools both in strong-field physics, driving x-
ray high-harmonic generation, and as the basis for widely tunable, if inefficient, ultrafast …

Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic
arrangement of microstructured holes located in the fiber's cladding. Light confinement is …
