Although diffractive spreading is an unavoidable feature of all wave phenomena, certain waveforms can attain propagation invariance. A lesser-explored strategy for achieving optical self-similar propagation exploits the modification of the spatiotemporal field structure when observed in reference frames moving at relativistic speeds. For such an observer, it is predicted that the associated Lorentz boost can bring to a halt the axial dynamics of a wave packet of an arbitrary profile. This…

Arbitrarily accelerating space-time wave packets.

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 constant

Accelerating and Decelerating Space-Time Optical Wave Packets in Free Space.

"space-time" wave packets in which each wavelength is associated with a prescribed spatial bandwidth enable the realization of optical acceleration and deceleration in free space, leading to group-velocity changes as high as ∼c observed over a distance of ∼20  mm infree space.

Optical wave-packet with nearly-programmable group velocities

During the process of Bessel beam generation in free space, spatiotemporal optical wave-packets with tunable group velocities and accelerations can be created by deforming pulse-fronts of injected

Synthesizing broadband propagation-invariant space-time wave packets using transmissive phase plates

Space-time wave packets are a class of pulsed optical beams that are diffractionfree and dispersion-free in free space by virtue of introducing a tight correlation between the spatial and temporal

Time-diffracting beams: On their nature, diffraction-free propagation as needles of light, and nonlinear generation.

We investigate on the properties of the recently introduced time-diffracting (TD) beams in free space. They are shown to be paraxial and quasi-monochromatic realizations of localized waves,

Consequences of non-differentiable angular dispersion in optics: tilted pulse fronts versus space-time wave packets.

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

Optical space-time wave packets having arbitrary group velocities in free space

Controlling the group velocity of an optical pulse typically requires traversing a material or structure whose dispersion is judiciously crafted. Alternatively, the group velocity can be modified in

Broadband space-time wave packets propagating 70  m.

The limits of the propagation distance for ST wave packets are explored using a specially designed phase plate inscribed by gray-scale lithography and having a laser-damage threshold of ∼0.5  J/cm2.

Spectral reorganization of space-time wave packets in presence of normal group-velocity dispersion

Space-time wave packets (STWPs) are pulsed beams that propagate invariantly (without diffraction or dispersion) in linear media. The behavior of STWPs in free space is now well-established, and

Meters-long propagation of diffraction-free space-time light-sheets.

This work synthesizes an ST wave packet in the form of a pulsed optical sheet of transverse spatial width ∼200 μm and spectral bandwidth of ∼2 nm, and observes its diffraction-free propagation for approximately 6 meters.



Generation of electron Airy beams

A non-spreading electron wavefunction that self-heals, restoring its original shape after passing an obstacle is observed, which opens up new avenues for steering electronic wave packets like their photonic counterparts, because the wave packets can be imprinted with arbitrary shapes or trajectories.

Diffraction-free pulsed optical beams via space-time correlations.

It is shown here that imposing a judicious correlation between spatial and spectral degrees of freedom of a pulsed beam can render its transverse spatial profile independent of location along the propagation axis, thereby arresting the spread of the time-averaged beam.

Nondiffracting accelerating wave packets of Maxwell's equations.

It is emphasized that in their scalar form, these beams are the exact solutions for nondispersive accelerating wave packets of the most common wave equation describing time-harmonic waves, which has profound implications to many linear wave systems in nature.

Spatiotemporal bessel beams: theory and experiments.

A family of dispersion-free and diffraction-free optical beams consisting in two-dimensional wave packets with a spatiotemporal Bessel (STB) profile propagating in media with anomalous dispersion and a comparison of the propagation of STBG beams with that of Gaussian wave packets is described.

Spatiotemporal vortex beams and angular momentum

We present a space-time generalization of the known spatial (monochromatic) wave vortex beams carrying intrinsic orbital angular momentum (OAM) along the propagation direction. Generic

Evidence of X-Shaped Propagation-Invariant Localized Light Waves

Ten years ago Durnin, Miceli, and Eberly [1] reported on the startling first experimental investigation of the socalled nondiffracting Bessel beam, which was formed from a cw laser light by an

Nonspreading wave packets

We show that for a wave ψ in the form of an Airy function the probability density ‖ψ‖2 propagates in free space without distortion and with constant acceleration. This ’’Airy packet’’ corresponds

Diffraction-free space–time light sheets

Diffraction-free optical beams propagate freely without change in shape and scale. Monochromatic beams that avoid diffractive spreading require two-dimensional transverse profiles and there are no

Controlling the velocity of ultrashort light pulses in vacuum through spatio-temporal couplings

Because of their broad spectral width, ultrashort lasers provide unique possibilities to shape light beams and control their properties, in particular through the use of spatio-temporal couplings. In

Ultrashort Tilted-Pulse-Front Pulses and Nonparaxial Tilted-Phase-Front Beams

Electromagnetic pulses with tilted pulse fronts are instrumental in enhancing the efficiency of many light–matter interaction processes, with prominent examples including terahertz generation by
