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…
Engineering the optical vacuum: Arbitrary magnitude, sign, and order of dispersion in free space using space-time wave packets
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…
