Integrated optics interferometric four telescopes nuller
Ronny Errmann, Stefano Minardi, Lucas Labadie +3
Nulling interferometry has been identified as a competitive technique for the detection of extrasolar planets. The technique consists in combining out-of-phase pairs of telescopes…
3D-integrated beam combiner for optical spectro-interferometry
Stefano Minardi, Allar Saviauk, Felix Dreisow +2
We present a compact setup based on a three-dimensional integrated optical component, allowing the mea- surement of spectrally resolved complex-visibilities for three channels of p…
Photonic Floquet Topological Insulators
Mikael C. Rechtsman, Julia M. Zeuner, Yonatan Plotnik +4
The topological insulator is a fundamentally new phase of matter, with the striking property that the conduction of electrons occurs only on its surface, not within the bulk, and t…
Classical analogue of displaced Fock states and quantum correlations in Glauber-Fock photonic lattices
Robert Keil, Armando Perez-Leija, Felix Dreisow +5
Coherent states and their generalisations, displaced Fock states, are of fundamental importance to quantum optics. Here we present a direct observation of a classical analogue for…
Amorphous Photonic Lattices: Band Gaps, Effective Mass and Suppressed Transport
Mikael Rechtsman, Alexander Szameit, Felix Dreisow +4
We present, theoretically and experimentally, amorphous photonic lattices exhibiting a band-gap yet completely lacking Bragg diffraction: 2D waveguides distributed randomly accordi…
Observation of localized modes at phase slips in two-dimensional photonic lattices
Alexander Szameit, Mario I. Molina, Matthias Heinrich +4
We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to…
