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…
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…
Measuring the true quality factor of an ultrafast photonic microcavity: homogeneous versus inhomogeneous broadening
Alex Hartsuiker, Allard P. Mosk, Julien Claudon +2
We have measured time-resolved the photon storage time and the quality factor of an ultrafast photonic cavity using an autocorrelator. The cavity consists of a -thick GaAs layer…
Kerr and free-carrier ultrafast all-optical switching of GaAs/AlAs nanostructures near the three-photon edge of GaAs
Alex Hartsuiker, Philip J. Harding, Yoanna-Reine Nowicki-Bringuier +2
We performed non-degenerate pump-probe experiments on a GaAs/AlAs photonic structure. We switched the photonic properties using the optical Kerr effect and free carriers excited by…
