Self-organized pattern formation in laser-induced multiphoton ionization
Robert Buschlinger, Stefan Nolte, Ulf Peschel
We use finite-difference time-domain modelling to investigate plasma generation induced by multi-photon absorption of intense laser light in dielectrics with tiny inhomogenities. P…
Functional plasmonic nano-circuits with low insertion and propagation losses
Arian Kriesch, Stanley P. Burgos, Daniel Ploss +3
We experimentally demonstrate plasmonic nano-circuits operating as sub-diffraction directional couplers optically excited with high efficiency from free-space using optical Yagi-Ud…
Nanointerferometric Amplitude and Phase Reconstruction of Tightly Focused Vector Beams
Thomas Bauer, Sergej Orlov, Ulf Peschel +2
Highly confined vectorial electromagnetic field distributions represent an excellent tool for detailed studies in nano-optics and high resolution microscopy, such as nonlinear micr…
Observation of Defect States in PT-Symmetric Optical Lattices
Alois Regensburger, Mohammad-Ali Miri, Christoph Bersch +4
We provide the first experimental demonstration of defect states in parity-time (PT) symmetric mesh-periodic potentials. Our results indicate that these localized modes can undergo…
