Observation of space-time surface plasmon polaritons
Naoki Ichiji, Hibiki Kikuchi, Murat Yessenov +3
Surface plasmon polaritons (SPPs) are surface-bound waves at metal-dielectric interfaces that exhibit strong out-of-plane field confinement, a key feature for applications is nano-…

Experimental realization of Lorentz boosts of space-time wave packets
Murat Yessenov, Miguel Romer, Naoki Ichiji +1
It is now well-understood that a Lorentz boost of a spatially coherent monochromatic optical beam yields a so-called space-time wave packet (STWP): a propagation-invariant pulsed b…

Spectral and temporal modulations of femtosecond SPP wave packets induced by resonant transmission/reflection interactions with metal-insulator-metal nanocavities
Naoki Ichiji, Yuka Otake, Atsushi Kubo
To study the dynamical optical interactions of nano-scaled metal-insulator-metal (MIM) structures in temporal-frequency domain, femtosecond surface plasmon polariton (SPP) wave pac…
