We describe theoretically and verify experimentally a novel, to the best of our knowledge, class of diffraction-free pulsed optical beams that are "omni-resonant": they have the remarkable property of transmission through planar Fabry-Perot resonators without spectral filtering, even if their bandwidth far exceeds the cavity linewidth. Ultrashort wave packets endowed with a specific spatiotemporal structure couple to a single resonant mode independent of its linewidth. We confirm that such…

Programmable omni-resonance using space–time fields
Omni-resonant wave packets are pulsed optical beams that couple to planar cavities even when the wave packet bandwidth far exceeds the cavity resonant linewidth by virtue of a precise spatiotemporal
V-Waves: Spatio-temporally induced group-velocity dispersion in free space
Introducing precise spatio-temporal structure into a pulsed optical field can lead to remarkable changes with its free propagation. ‘Space-time’ (ST) wave packets, for example, propagate rigidly at a
Temporal Talbot effect in free space.
TLDR
This work demonstrates for the first time, to the best of the knowledge, the temporal Talbot effect in free space by employing dispersive space-time wave packets, whose spatiotemporal structure induces group-velocity dispersion of controllable magnitude and sign infree space.
Broadband Omni-resonant Coherent Perfect Absorption in Graphene
Coherent perfect absorption (CPA) refers to interferometrically induced complete absorption of incident light by a partial absorber independently of its intrinsic absorption (which may be vanishingly
Coherent perfect absorption in resonant materials
Coherent perfect absorption (CPA) is an interferometric effect that guarantees full absorption in a lossy layer independently of its intrinsic losses. To date, it has been observed only at a single
A universal angular-dispersion synthesizer
We uncover a surprising gap in optics with regards to angular dispersion (AD) that has persisted for decades. A systematic examination of pulsed optical-field configurations classified according to
Canceling and inverting normal and anomalous group-velocity dispersion using space-time wave packets
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 dispersion reduces the
Roadmap on multimode light shaping
Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously combining different
Spectrally recycling space-time wave packets
Space-time (ST) wave packets are propagation-invariant pulsed optical beams that travel rigidly in linear media without diffraction or dispersion at a potentially arbitrary group velocity. These
Axial Spectral Encoding of Space-Time Wave Packets
Space-time (ST) wave packets are propagation-invariant pulsed optical beams whose group velocity can be tuned in free space by tailoring their spatio-temporal spectral structure. To date, efforts on

TLDR
This approach severs the link between the resonance bandwidth and the cavity-photon lifetime, thereby promising resonant enhancement of linear and nonlinear optical effects over broad bandwidths in ultrathin devices.

Experimental evidence of the optical realizability of the "fundamental" special case of the LW's-the focus wave modes is reported on.
Spatiotemporal diffraction-free pulsed beams in free-space of the Airy and Bessel type.
TLDR
It is shown that, by appropriate spectral excitations, the three different types of conic sections can lead to optical waves of the Bessel, Airy, and modified Bessel types, respectively.
Airy Wave Packets Accelerating in Space-Time.
TLDR
An acceleration-free Airy wave packet is synthesized that travels in a straight line by deforming its spatiotemporal spectrum to reproduce the impact of a Lorentz boost, leading to "time diffraction" manifested in self-acceleration observed in the propagating Airy Wavey wave-packet frame.

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

It is shown that wavelength dispersion of the cone angle of axicons and circular diffraction gratings can be used to generate good approximation to focus wave modes.
Self-healing of space-time light sheets.
TLDR
It is demonstrated here experimentally and computationally that ST light sheets exhibit self-healing properties upon traversing obstacles in the form of opaque obstructions, indicating the robustness of ST wave packets and their potential utility for deep illumination and imaging in scattering media, such as biological tissues.
What is the maximum differential group delay achievable by a space-time wave packet in free space?
TLDR
This paper investigates theoretically and experimentally the maximum achievable group delay that realistic finite-energy space-time wave packets can achieve with respect to a reference pulse traveling at the speed of light and finds that this delay is determined solely by the spectral uncertainty in the association between the spatial frequencies and wavelengths underlying the wave packet spatio-temporal spectrum.
