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…
