Ultrafast lasers reaching extremely high powers within short fractions of time enable a
plethora of applications. They grant advanced material processing capabilities, are effective …

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light
pulses. Currently two methods are capable of generating such pulses: post compression of …

Improved analytical tools are urgently required to identify degradation and failure
mechanisms in Li-ion batteries. However, understanding and ultimately avoiding these …

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

Optical soliton dynamics can cause extreme alteration of the temporal and spectral shape of
a propagating light pulse. This occurs at up to kilowatt peak powers in glass-core optical …

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

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 …

Multimode fibres are of interest for next-generation telecommunications systems and the
construction of high-energy fibre lasers. However, relatively little work has explored …

In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

We report a hollow-core photonic crystal fiber that is engineered so as to strongly suppress
higher-order modes, ie, to provide robust LP 01 single-mode guidance in all the wavelength …
