Sub-thermal to super-thermal light statistics from a disordered lattice via deterministic control of excitation symmetry
H. E. Kondakci, A. Szameit, A. F. Abouraddy +2
Monochromatic coherent light traversing a disordered photonic medium evolves into a random field whose statistics are dictated by the disorder level. Here we demonstrate experiment…
Hanbury Brown and Twiss anticorrelation in disordered photonic lattices
H. Esat Kondakci, Lane Martin, Robert Keil +5
We report measurements of Hanbury Brown and Twiss correlation of coherent light transmitted through disordered one-dimensional photonic lattices. Although such a lattice exhibits t…
Spatial Goos-Hänchen shift in photonic graphene
Simon Grosche, Alexander Szameit, Marco Ornigotti
We present a theoretical study of the spatial Goos-Hänchen shift occurring at the interface between two different photonic graphene lattices. Numerical simulations of light propaga…
Hybrid waveguide-bulk multi-path interferometer with switchable amplitude and phase
Robert Keil, Thomas Kaufmann, Thomas Kauten +5
We design and realise a hybrid interferometer consisting of three paths based on integrated as well as on bulk optical components. This hybrid construction offers a good compromise…
Squeezing of X waves with orbital angular momentum
Marco Ornigotti, Leone di Mauro Villari, Alexander Szameit +1
Multi-level quantum protocols may potentially supersede standard quantum optical polarization-encoded protocols in terms of amount of information transmission and security. However…
Observation of dipolar transport in one-dimensional photonic lattices
Camilo Cantillano, Luis Morales-Inostroza, Bastián Real +4
We experimentally study the transport prop- erties of dipolar and fundamental modes on one di- mensional (1D) coupled waveguide arrays. By carefully modulating a wide optical beam,…
Observation of photonic anomalous Floquet Topological Insulators
Lukas J. Maczewsky, Julia M. Zeuner, Stefan Nolte +1
Commonly, a two-dimensional topological insulator is characterized by non-zero Chern numbers associated with its band structure. In our work, we present the experimental demonstrat…
Topological Protection of Photonic Path Entanglement
Mikael C. Rechtsman, Yaakov Lumer, Yonatan Plotnik +3
The recent advent of photonic topological insulators has opened the door to using the robustness of topologically protected transport (originated in the domain of condensed matter…
Trapping atoms in the evanescent field of laser written wave guides
Dario Jukic, A Moqanaki, P Walther +3
We analyze evanescent fields of laser written waveguides and show that they can be used to trap atoms close to the surface of an integrated optical atom chip. In contrast to subwav…
Transport in Sawtooth photonic lattices
Steffen Weimann, Luis Morales-Inostroza, Bastián Real +3
We investigate, theoretically and experimentally, a photonic realization of a Sawtooth lattice. This special lattice exhibits two spectral bands, with one of them experiencing a co…
Cylindrically Polarized Nondiffracting Optical Pulses
Marco Ornigotti, Claudio Conti, Alexander Szameit
We extend the concept of radially and azimuthally polarized optical beams to the polychromatic domain by introducing cylindrically polarized nondiffracting optical pulses. In parti…
