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 …

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 …

Optical wave packets that are localized in space and time, but nevertheless overcome
diffraction and travel rigidly in free space, are a long sought-after field structure with …

Talbot effect, characterized by the replication of a periodic optical field in a specific plane, is
governed by diffraction and dispersion in the spatial and temporal domains, respectively. In …

With their self-tuned time-varying responses, waveform-selective metasurfaces embedded
with nonlinear electronics have shown fascinating applications, including distinguishing …

Spatiotemporal sculpturing of light pulses with sophisticated structures on demand is one
major goal of the everlasting pursuit of ultrafast information transmission and processing as …

All known realizations of optical wave packets that accelerate along their propagation axis,
such as Airy wave packets in dispersive media or wave-front-modulated X-waves, exhibit a …

Introducing precise spatiotemporal structure into a pulsed optical field can lead to
remarkable changes with its free propagation.“Space-time”(ST) wave packets, for example …

Conventional diffractive and dispersive devices introduce angular dispersion (AD) into
pulsed optical fields, thus producing so-called 'tilted pulse fronts'. Naturally, it is always …

Angular dispersion can counterbalance normal group‐velocity dispersion (GVD) that
increases the wave‐vector length in a dispersive medium. By tilting the wave vector, angular …
