Non-invasive light observer
Francesco Morichetti, Stefano Grillanda, Marco Carminati +5
Photonic technologies lack non-invasive monitoring tools to inspect the light inside optical waveguides. This is one of the main barriers to large scale of integration, even though…
Optical analogue of spontaneous symmetry breaking induced by tachyon condensation in amplifying plasmonic arrays
A. Marini, Tr. X. Tran, S. Roy +2
We study analytically and numerically an optical analogue of tachyon condensation in amplifying plasmonic arrays. Optical propagation is modeled through coupled-mode equations, whi…
Optical analogue of relativistic Dirac solitons in binary waveguide arrays
Truong X. Tran, Stefano Longhi, Fabio Biancalana
We study analytically and numerically an optical analogue of Dirac solitons in binary waveguide arrays in presence of Kerr nonlinearity. Pseudo-relativistic soliton solutions of th…
Blackbody emission from light interacting with an effective moving dispersive medium
M. Petev, N. Westerberg, D. Moss +5
Intense laser pulses excite a nonlinear polarisation response that may create an effective flowing medium and, under appropriate conditions, a blocking horizon for light. Here we a…
Carrier-envelope phase effects on the strong-field photoemission of electrons from metallic nanostructures
Bjoern Piglosiewicz, Slawa Schmidt, Doo Jae Park +5
Sharp metallic nanotapers irradiated with few-cycle laser pulses are emerging as a source of highly confined coherent electron wavepackets with attosecond duration and strong direc…
