Nonlinear Quantum Electrodynamics of Epsilon-Near-Zero Nanocavities
Luca Dal Negro, Riccardo Franchi, Marco Ornigotti
We investigate single-photon nonlinear refractive index change and frequency shift of Epsilon-Near-Zero (ENZ) sub-wavelength nanocavities. We apply the rigorous quantum Langevin-no…
Field theory description of the non-perturbative optical nonlinearity of epsilon-near-zero media
Yaraslau Tamashevich, Tornike Shubitidze, Luca Dal Negro +1
In this paper we introduce a fully non-perturbative approach for the description of the optical nonlinearity of epsilon-near-zero (ENZ) media. In particular, based on the rigorous…
Time-varying media, relativity, and the arrow of time
Matias Koivurova, Charles W. Robson, Marco Ornigotti
We study the implications of time-varying wave mechanics, and show how the standard wave equation is modified if the speed of a wave is not constant in time. In particular, waves w…
High-accuracy longitudinal position measurement using self-accelerating light
Shashi Prabhakar, Stephen Plachta, Marco Ornigotti +1
Radially self-accelerating light exhibits an intensity pattern that describes a spiraling trajectory around the optical axis as the beam propagates. In this article, we show in sim…
Localized waves carrying orbital angular momentum in optical fibers
Paula Nuño Ruano, Charles W. Robson, Marco Ornigotti
We consider the effect of orbital angular momentum (OAM) on localized waves in optical fibers using theory and numerical simulations, focusing on splash pulses and focus wave modes…
Interacting ring-Airy beams in nonlinear media
Charles W. Robson, Marco Ornigotti
The interactions between copropagating ring-Airy beams in a (2+1)-dimensional Kerr medium are numerically investigated for the first time. It is shown that two overlapping ring-Air…
