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 temporal characterization of ultrafast laser pulses has become a cornerstone capability
of ultrafast optics laboratories and is routine both for optimizing laser pulse duration and …

Introducing angular dispersion into a pulsed field tilts the pulse front with respect to the
phase front. There exists between the angular dispersion and pulse-front tilt a universal …

The group velocity of 'space-time'wave packets–propagation-invariant pulsed beams
endowed with tight spatio-temporal spectral correlations–can take on arbitrary values in free …

Spatial structuring of an optical pulse can lead in some cases upon free propagation to
changes in its temporal profile. For example, introducing conventional angular dispersion …

Space–time (ST) wave packets are coherent pulsed beams that propagate diffraction free
and dispersion free by virtue of tight correlations introduced between their spatial and …

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 …

We introduce the unique class of propagation-invariant surface plasmon polaritons (SPPs)
representing pulsed surface wave packets propagating along unpatterned metal–dielectric …

An optical buffer featuring a large delay-bandwidth-product—a critical component for future
all-optical communications networks—remains elusive. Central to its realization is a …

The propagation distance of a pulsed beam in free space is ultimately limited by diffraction
and space-time coupling.“Space-time”(ST) wave packets are pulsed beams endowed with …
