Skyrmions are topologically stable quasiparticles that have been predicted and
demonstrated in quantum fields, solid-state physics and magnetic materials, but only …

Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Structured light recently highlighted the higher-dimensional control with many tailored
degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular …

Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents a
major goal of the everlasting pursue of ultra-fast information transmission and processing as …

Transverse electromagnetic waves are important carriers of information and energy. In 1996,
Hellwarth and Nouchi theoretically identified a radically different, non-transverse type of …

Structured light fields embody strong spatial variations of polarization, phase, and amplitude.
Understanding, characterization, and exploitation of such fields can be achieved through …

Toroidal electromagnetic pulses have been recently reported as nontransverse, space-time
nonseparable topological excitations of free space. However, their propagation dynamics …

A step towards the next generation of high-capacity, noise-resilient communication and
computing technologies is a substantial increase in the dimensionality of information space …

Optical metrology is a well-established subject, dating back to early interferometry
techniques utilizing light's linear momentum through fringes. In recent years, significant …
