All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

Light sheet fluorescence microscopy (LSFM) uses a thin sheet of light to excite only
fluorophores within the focal volume. Light sheet microscopes (LSMs) have a true optical …

Structured light, especially beams carrying orbital angular momentum (OAM), has gained
much interest due to its unique amplitude and phase structures. In terms of communication …

Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

The fractional Schrödinger equation (FSE)—a natural extension of the standard Schrödinger
equation—is the basis of fractional quantum mechanics. It can be obtained by replacing the …

Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

Planar optical elements that can manipulate the multidimensional physical parameters of
light efficiently and compactly are highly sought after in modern optics and nanophotonics. In …

We present a survey of some recent theoretical and experimental studies on nonlinear
waves that form and propagate in a broad class of optical and matterwave media. The article …

The techniques of optical beam sha** have enabled progress in a broad range of
interdisciplinary science and engineering, owing to the unique properties and promising …
