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…
Transverse spin angular momentum of space-time surface plasmon polariton wave packet
Naoki Ichiji, Daigo Oue, Murat Yessenov +3
In addition to longitudinal spin angular momentum (SAM) along the axis of propagation of light, spatially structured electromagnetic fields such as evanescent waves and focused bea…
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…
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…
Resonance order-dependent plasmon-induced transparency in orthogonally-arranged nanoscale cavities
Naoki Ichiji, Atsushi Kubo
In this study, we investigate plasmon-induced transparency (PIT) in a resonator structure consisting of two orthogonally-arranged metal-insulator-metal (MIM) nanocavities with the…
Spatiotemporal control of surface plasmon polariton wave packets with nanocavities
Naoki Ichiji, Yuka Otake, Atsushi Kubo
Modulation of the optical index by means of atomic and material resonances provides a basis for controlling light propagation in natural and artificially fabricated materials. In a…
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…
