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…
Quantum walks of correlated photon pairs in two-dimensional waveguide arrays
Konstantinos Poulios, Robert Keil, Daniel Fry +9
We demonstrate quantum walks of correlated photons in a 2D network of directly laser written waveguides coupled in a 'swiss cross' arrangement. The correlated detection events show…
Edge states protected by chiral symmetry in disordered photonic graphene
Julia M. Zeuner, Mikael C. Rechtsman, Stefan Nolte +1
We experimentally investigate the impact of uncorrelated composite and structural disorder in photonic graphene. We find that in case of structural disorder not only chiral symmetr…
Compact surface Fano states embedded in the continuum of waveguide arrays
Steffen Weimann, Yi Xu, Robert Keil +5
We describe theoretically and observe experimentally the formation of a surface state in a semi-infnite waveguide array with side-coupled waveguide, designed to simultaneously achi…
Self-trapping threshold in disordered nonlinear photonic lattices
U. Naether, M. Heinrich, Y. Lahini +4
We investigate numerically and experimentally the influence of coupling disorder on the self-trapping dynamics in nonlinear one-dimensional optical waveguide arrays. The existence…
Hybrid Bloch-Anderson localization of light
Simon Stutzer, Yaroslav V. Kartashov, Victor A. Vysloukh +4
We investigate the interplay of Bloch oscillations and Anderson localization in optics. Gradual washing out of Bloch oscillations and the formation of nearly stationary averaged in…
