Abstract 2D and 3D solitons and related states, such as quantum droplets, can appear in
optical systems, atomic Bose–Einstein condensates (BECs) and liquid crystals, among other …

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 …

We perform a survey of some recent theoretical and experimental studies on
multidimensional (two-and three-dimensional) localized structures in optical and matter …

We propose the generation of 3D linear light bullets propagating in free space using a single
passive nonlocal optical surface. The nonlocal nanophotonics can generate space–time …

We present the first experimental evidence, supported by theory and simulation, of
spatiotemporal optical vortices (STOVs). A STOV is an optical vortex with phase and energy …

Strong terahertz (THz) electric and magnetic transients open up new horizons in science
and applications. We review the most promising way of achieving sub-cycle THz pulses with …

We measure the nonlinear refractive index coefficients in N_2, O_2, and Ar from visible
through mid-infrared wavelengths (λ= 0.4–2.4 μm). The wavelengths investigated …

Transition-metal dichalcogenides (TMDCs) and black phosphorus (BP) are typical 2D
materials with layer-dependent bandgaps, which are emerging as promising saturable …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

Filamentation of ultra-short TW-class lasers recently opened new perspectives in
atmospheric research. Laser filaments are self-sustained light structures of 0.1–1 mm in …
