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 …

Sculpting light in space and time can provide unprecedented opportunities in many areas of
science and technology, ranging from extreme nonlinear optics and quantum networks to …

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 …

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 …

Light that carries spatiotemporal orbital angular momentum (ST-OAM) makes possible new
types of optical vortices arising from transverse OAM. ST-OAM pulses exhibit novel …

The spatiotemporal optical vortex (STOV) is unique, owing to its phase singularity in the
space–time domain, and it can carry transverse orbital angular momentum (OAM) …

In this paper, we study the behaviors of spatiotemporal optical vortex (STOV) beams
propagating in linear dispersive media. Starting with the Fresnel diffraction integral, we …

Traditionally, manipulation of spatiotemporal coupling (STC) of the ultrafast light fields can
be actualized in the space-spectrum domain with some 4-f pulse shapers, which suffers …

Spin and orbital angular momenta are two of the most fundamental physical quantities that
describe the complex dynamic behaviors of optical fields. A strong coupling between these …

Optical vortices have myriad applications in photonics. Very recently, promising concepts of
spatiotemporal optical vortex (STOV) pulses based on the phase helicity in the space–time …
