Theory of space-time supermodes in planar multimode waveguides
Abbas Shiri, Kenneth L. Schepler, Ayman F. Abouraddy
When an optical pulse is focused into a multimode waveguide or fiber, the energy is divided among the available guided modes. Consequently, the initially localized intensity spread…
Exciting space-time surface plasmon polaritons by irradiating a nanoslit structure
Naoki Ichiji, Murat Yessenov, Kenneth L. Schepler +2
Space-time (ST) wave packets are propagation-invariant pulsed optical beams that travel freely in dielectrics at a tunable group velocity without diffraction or dispersion. Because…
Propagation-invariant space-time supermodes in a multimode waveguide
Abbas Shiri, Scott Webster, Kenneth L. Schepler +1
When an optical pulse is spatially localized in a highly multimoded waveguide, its energy is typically distributed among a multiplicity of modes, thus giving rise to a speckled tra…
Observation of ultrabroadband striped space-time surface plasmon polaritons
Naoki Ichiji, Hibiki Kikuchi, Murat Yessenov +3
Because surface plasmon polaritons (SPPs) are surface waves characterized by one free transverse dimension, the only monochromatic diffraction-free spatial profiles for SPPs are co…
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…
