Quantitative measurement of combustion gases in harsh environments using NDIR spectroscopy
Christian Niklas, Stephan Bauke, Fabian Müller +3
The global climate change calls for a more environmental friendly use of energy and has led to stricter limits and regulations for the emissions of various greenhouse gases. Conseq…
Programmable two-photon quantum interference in channels in opaque scattering media
Tom A. W. Wolterink, Ravitej Uppu, Georgios Ctistis +3
We investigate two-photon quantum interference in an opaque scattering medium that intrinsically supports transmission channels. By adaptive spatial phase-modulation of the…
Optimal all-optical switching of a microcavity resonance in the telecom range using the electronic Kerr effect
Emre Yüce, Georgios Ctistis, Julien Claudon +2
We have switched GaAs/AlAs and AlGaAs/AlAs planar microcavities that operate in the "Original" (O) telecom band by exploiting the instantaneous electronic Kerr effect. We observe t…
Observation of nonlinear bands in near-field scanning optical microscopy of a photonic-crystal waveguide
Amandev Singh, Georgios Ctistis, Simon R. Huisman +4
We have measured the photonic bandstructure of GaAs photonic-crystal waveguides with high energy and momentum resolution using near-field scanning optical microscopy. Intriguingly,…
Nonlinear frequency conversion is controlled by vacuum fluctuations
Emre Yüce, Georgios Ctistis, Julien Claudon +2
Ever since the advent of nonlinear optics, the generation of light by frequency-conversion is drawing continued attention, and leading to emerging applications such as supercontinu…
Differential ultrafast all-optical switching of the resonances of a micropillar cavity
Henri Thyrrestrup, Emre Yüce, Georgios Ctistis +3
We perform frequency- and time-resolved all-optical switching of a GaAs-AlAs micropillar cavity using an ultrafast pump-probe setup. The switching is achieved by two-photon excitat…
All-optical Switching of a Microcavity Repeated at Terahertz Rates
Emre Yüce, Georgios Ctistis, Julien Claudon +6
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We exploit the virtually instantaneous e…
Competition between electronic Kerr and free carrier effects in an ultimate-fast optically switched semiconductor microcavity
E. Yüce, G. Ctistis, J. Claudon +4
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We concentrate on ultimate-fast optical…
Surface plasmons and magneto-optic activity in hexagonal Ni anti-dot arrays
Evangelos Th. Papaioannou, Vassilios Kapaklis, Emil Melander +7
The influence of surface plasmons on the magneto-optic activity in a two-dimensional hexagonal array is addressed. The experiments were performed using hexagonal array of circular…
Ultimate fast optical switching of a planar microcavity in the telecom wavelength range
Georgios Ctistis, Emre Yüce, Alex Hartsuiker +4
We have studied a GaAs-AlAs planar microcavity with a resonance near 1300 nm in the telecom range by ultrafast pump-probe reflectivity. By the judicious choice of pump frequency, w…
Optical characterization and selective addressing of the resonant modes of a micropillar cavity with a white light beam
Georgios Ctistis, Alex Hartsuiker, Edwin van der Pol +3
We have performed white-light reflectivity measurements on GaAs/AlAs micropillar cavities with diameters ranging from 1 μm up to 20 μm. We are able to resolve the spatial field dis…
