Motion of Spin Polariton Bullets in Semiconductor Microcavities

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...

Coherent oscillations between orbital angular momentum polariton states in an elliptic resonator

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

We optically excited the eigenmodes of an elliptic resonator in a semiconductor microcavity. Using a pulsed excitation, we created a superposition of eigenmodes, and imaged the temporal evolution of the coherent emission pattern. A semiconductor quantum we ...

Coherent oscillations between polariton vortex and anti-vortex states in an elliptical resonator

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

In this experimental work, we optically excite the eigenmodes of an elliptical resonator in a semiconductor micro-cavity. Using a pulsed excitation, we create a superposition of eigenmodes, and image the time evolution of the coherent emission pattern. Osc ...

Direct comparison of phase-sensitive vibrational sum frequency generation with maximum entropy method: Case study of water

Sylvie Roke

We present a direct comparison of phase sensitive sum-frequency generation experiments with phase reconstruction obtained by the maximum entropy method. We show that both methods lead to the same complex spectrum. Furthermore, we discuss the strengths and ...

Insect Vision: A Few Tricks to Regulate Flight Altitude

Dario Floreano, Jean-Christophe Zufferey

A recent study sheds new light on the visual cues used by Drosophila to regulate flight altitude. The striking similarity with previously identified steering mechanisms provides a coherent basis for novel models of vision-based flight control in insects an ...

Coherent Oscillations in an Exciton-Polariton Josephson Junction

Benoît Marie Joseph Deveaud, Konstantinos Lagoudakis, Barbara Pietka

We report on the observation of spontaneous coherent oscillations in a microcavity polariton bosonic Josephson junction. Condensation of exciton polaritons here takes place under incoherent excitation in a double potential well naturally formed in the diso ...

Higher order coherence of exciton-polariton condensates

Paolo Schwendimann, Antonio Quattropani

The second- and third-order coherence functions g((n))(0) (n= 2 and 3) of an exciton-polariton condensate are measured and compared to the theory. Contrary to an ideal photon laser, deviation from unity in the second- and third-order coherence functions is ...

THE VISNET II DVC CODEC: ARCHITECTURE, TOOLS AND PERFORMANCE

Touradj Ebrahimi, Frédéric Dufaux

This paper introduces the VISNET II DVC codec. This co-dec achieves very high RD performance thanks to the efficient combination of many state-of-the-art coding tools into a fully practical video codec. Experimental results show that the proposed DVC codec ...

Optical Demultiplexing of 320 Gb/s to 8x40 Gb/s in Single Parametric Gate

Camille Sophie Brès

The first experimental demonstration of 320Gb/s demultiplexing to eight simultaneous always-on 40Gb/s tributaries with near-zero latency is reported. Error-free demultiplexing is achieved by a single parametric processor operating in copy-and-sample mode ...
