Sparsity-based single-shot sub-wavelength coherent diffractive imaging
A. Szameit, Y. Shechtman, E. Osherovich +13
We present the experimental reconstruction of sub-wavelength features from the far-field intensity of sparse optical objects: sparsity-based sub-wavelength imaging combined with ph…
Controlling the Dynamics of Quantum Mechanical Systems Sustaining Dipole-Forbidden Transitions via Optical Nanoantennas
Robert Filter, Stefan Mühlig, Toni Eichelkraut +2
We suggest to excite dipole-forbidden transitions in quantum-mechanical systems by using appropriately designed optical nanoantennas. The antennas are tailored such that their near…
Solitons in geometric potentials
Yaroslav V. Kartashov, Alexander Szameit, Robert Keil +2
We show that the geometrically-induced potential existing in undulated slab waveguides dramatically affects the properties of solitons. In particular, whereas solitons residing in…
Tailoring THz radiation by controlling tunnel photoionization events in gases
I. Babushkin, S. Skupin, A. Husakou +4
Applications ranging from nonlinear terahertz spectroscopy to remote sensing require broadband and intense THz radiation which can be generated by focusing two-color laser pulses i…
Circular Optical Nanoantennas: An Analytical Theory
Robert Filter, Jing Qi, Carsten Rockstuhl +1
An entirely analytical theory is provided for describing the resonance properties of optical nanoantennas made of a stack of homogeneous discs, i.e. circular patch nanoantennas. It…
Analytical Approximations of Whispering gallery Modes in Anisotropic Ellipsoidal Resonators
Marco Ornigotti, Andrea Aiello
Numerical evolutions of whispering gallery modes of both isotropic and anisotropic spheroidal resonators are presented and used to build analytical approximations of these modes. S…
Generation and near-field imaging of Airy surface plasmons
Alexander Minovich, Angela E. Klein, Norik Janunts +3
We demonstrate experimentally the generation and near-field imaging of nondiffracting surface waves - plasmonic Airy beams, propagating on the surface of a gold metal film. The Air…
Waveguide grating mirror in a fully suspended 10 meter Fabry-Perot cavity
Daniel Friedrich, Bryan W. Barr, Frank Brückner +14
We report on the first demonstration of a fully suspended 10m Fabry-Perot cavity incorporating a waveguide grating as the coupling mirror. The cavity was kept on resonance by readi…
Point-by-point inscription of apodized fiber Bragg gratings
Robert J. Williams, Christian Voigtländer, Graham D. Marshall +4
We demonstrate apodized fiber Bragg gratings inscribed with a point-by-point technique. We tailor the grating phase and coupling amplitude through precise control over the longitud…
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…
Real-time determination of laser beam quality by modal decomposition
Oliver A. Schmidt, Christian Schulze, Daniel Flamm +4
We present a real-time method to determine the beam propagation ratio M2 of laser beams. The all-optical measurement of modal amplitudes yields M2 parameters conform to the ISO sta…
