Observation of spatially structured Montgomery effect in free space
Murat Yessenov, Luca Sacchi, Alfonso Palmieri +3
We report the first direct observation of the spatially structured Montgomery effect, a lensless self-imaging phenomenon that generalizes the Talbot effect to aperiodic structures,…
Broadband entangled-photon omni-resonance in a planar optical cavity
Bryan L. Turo, Layton A. Hall, Bahaa E. A. Saleh +1
Resonant field enhancement in an optical cavity is a promising pathway towards realizing optical nonlinearities at the few-photon level. This quest is hampered by inevitable narrow…
Bending space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
Optical beams with certain asymmetric profiles, such as the Airy beam, can depart from rectilinear propagation and instead travel along curved (typically parabolic) trajectories. H…
Universality and non-differentiability: A new perspective on angular dispersion in optics
Layton A. Hall, Murat Yessenov, Kenneth L. Schepler +1
Angular dispersion (AD) is a ubiquitous phenomenon in optics after light traverses a diffractive or dispersive device, whereby each wavelength propagates at a different angle. AD i…
Long-distance axial spectral encoding using space-time wave packets
Layton A. Hall, Murat Yessenov, Miguel A. Romer +1
Space-time wave packets (STWPs) are pulsed optical beams whose spatiotemporal structure enables propagation invariance. However, STWPs allow for a unique propagation configuration…
Ultrafast space-time optical merons in momentum-energy space
Murat Yessenov, Ahmed H. Dorrah, Cheng Guo +7
Skyrmions, topologically non-trivial localized spin structures, are fertile ground for exploring emergent phenomena in condensed matter physics and next-generation magnetic-memory…
Synthesis and characterization of space-time light sheets: A tutorial
Miguel A. Romer, Layton A. Hall, Ayman F. Abouraddy
Space-time wave packets (STWPs) are a new class of pulsed optical beams with many unique and intriguing attributes, including propagation invariance and tunable group velocity in l…
Abrupt X-to-O-wave structural field transition in presence of anomalous dispersion
Layton A. Hall, Ayman F. Abouraddy
All linear, propagation-invariant, paraxial pulsed beams are spatiotemporally X-shaped (conical waves) in absence of group-velocity dispersion (GVD), or in presence of normal GVD.…
Observation of optical de Broglie-Mackinnon wave packets
Layton A. Hall, Ayman F. Abouraddy
de Broglie wave packets accompanying moving particles are dispersive and lack an intrinsic length scale dictated solely by the particle mass and velocity. Mackinnon proposed almost…
Omni-resonant imaging across the visible
Layton A. Hall, Abbas Shiri, Ayman F. Abouraddy
Resonant field enhancement in optical cavities is provided over only narrow linewidths and for specific spatial modes. Consequently, spectrally restrictive planar Fabry-P{é}rot cav…
Space-time wave packets propagating a kilometer in air
Layton A. Hall, Miguel A. Romer, Bryan L. Turo +3
We report on the diffraction-free propagation of space-time wave packets (STWPs) -- a class of propagation-invariant pulsed beams -- for km in an open-air laser range in…
Non-differentiable angular dispersion as an optical resource
Layton A. Hall, Ayman F. Abouraddy
Introducing angular dispersion into a pulsed field associates each frequency with a particular angle with respect to the propagation axis. A perennial yet implicit assumption is th…
Spectral reorganization of space-time wave packets in presence of normal group-velocity dispersion
Layton A. Hall, Ayman F. Abouraddy
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-est…
Canceling and inverting normal and anomalous group-velocity dispersion using space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
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 dispe…
Space-time wave packets
Murat Yessenov, Layton A. Hall, Kenneth L. Schepler +1
"Space-time" (ST) wave packets constitute a broad class of pulsed optical fields that are rigidly transported in linear media without diffraction or dispersion, and are therefore p…
A universal angular-dispersion synthesizer
Layton A. Hall, Ayman F. Abouraddy
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 classi…
The consequences of non-differentiable angular dispersion in optics: Tilted pulse fronts versus space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
Conventional diffractive and dispersive devices introduce angular dispersion (AD) into pulsed optical fields thus producing so-called 'tilted pulse fronts'. Naturally, it is always…
Arbitrarily accelerating space-time wave packets
Layton A. Hall, Murat Yessenov, Ayman F. Abouraddy
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…
Realizing normal group-velocity dispersion in free space via angular dispersion
Layton A. Hall, Ayman F. Abouraddy
It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive compone…
V-Waves: Spatio-temporally induced group-velocity dispersion in free space
Layton A. Hall, Ayman F. Abouraddy
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, pro…
Temporal Talbot effect in free space
Layton A. Hall, Sergey A. Ponomarenko, Ayman F. Abouraddy
The temporal Talbot effect refers to the periodic revivals of a pulse train propagating in a dispersive medium, and is a temporal analog of the spatial Talbot effect with group-vel…

Murat Yessenov, Layton A. Hall, Ayman F. Abouraddy
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 in…
The space-time Talbot effect
Layton A. Hall, Murat Yessenov, Sergey A. Ponomarenko +1
The Talbot effect, epitomized by periodic revivals of a freely evolving periodic field structure, has been observed with waves of diverse physical nature in space and separately in…
Space-time wave packets violate the universal relationship between angular dispersion and pulse-front tilt
Layton A. Hall, Murat Yessenov, Ayman F. Abouraddy
Introducing angular dispersion into a pulsed field tilts the pulse front with respect to the phase front. There exists between the angular dispersion and the pulse-front tilt a uni…
