Over the last dozen years, the area of accelerating waves has made considerable advances
not only in terms of fundamentals and experimental demonstrations, but also in connection …

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 …

Diffraction-free optical beams propagate freely without change in shape and scale.
Monochromatic beams that avoid diffractive spreading require two-dimensional transverse …

Introducing correlations between the spatial and temporal degrees of freedom of a pulsed
optical beam (or wave packet) can profoundly alter its propagation in free space. Indeed …

Diffraction places a fundamental limitation on the distance an optical beam propagates
before its size increases and spatial details blur. We show here that imposing a judicious …

Although diffractive spreading is an unavoidable feature of all wave phenomena, certain
waveforms can attain propagation invariance. A lesser-explored strategy for achieving …

In light of pending capacity crunch in information era, orbital-angular-momenta-carrying
vortex beams are gaining traction thanks to enlarged transmission capability. However, high …

Light is confined transversely and delivered axially in a waveguide. However, waveguides
are lossy static structures whose modal characteristics are fundamentally determined by …

This book is devoted to the consideration of unusual laser beams–vortex or singular beams.
It contains many numerical examples, which clearly show how the phase of optical vortices …

Modern nanophotonic and meta-optical devices utilize a tremendous number of structural
degrees of freedom to enhance light–matter interactions. A fundamental question is how …
