Three-Dimensional Light Bullets in Arrays of Waveguides
Stefano Minardi, Falk Eilenberger, Yaroslav V. Kartashov +10
We report the first experimental observation of 3D-LBs, excited by femtosecond pulses in a system featuring quasi-instantaneous cubic nonlinearity and a periodic, transversally-mod…
Doubly resonant optical nanoantenna arrays for polarization resolved measurements of surface-enhanced Raman scattering
J. Petschulat, D. Cialla, N. Janunts +9
We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic resonances, making them favorable bio-sensing substrates. Besides the two localized plasmonic dipole…
Soliton excitation in waveguide arrays with an effective intermediate dimensionality
A. Szameit, Y. V. Kartashov, F. Dreisow +7
We reveal and observe experimentally significant modifications undertaken by discrete solitons in waveguide lattices upon the continuous transformation of the lattice structure fro…
Photonic Bloch oscillations and Zener tunneling in two-dimensional optical lattices
Henrike Trompeter, Wieslaw Krolikowski, Dragomir N. Neshev +6
We report on the first experimental observation of photonic Bloch oscillations and Zener tunneling in two-dimensional periodic systems. We study the propagation of an optical beam…
