Counter-directional polariton coupler

Hugo Pierre Alexandre Flayac, Christoph Schneider

We report on an on-chip routing device for propagating condensates of exciton-polaritons. This counter-directional coupler implements signal control by a photonic microdisk potential, which couples two lithographically defined waveguides and reverses the c ...

Observation of the Unconventional Photon Blockade

Vincenzo Savona, Hugo Pierre Alexandre Flayac

We observe the unconventional photon blockade effect in quantum dot cavity QED, which, in contrast to the conventional photon blockade, operates in the weak coupling regime. A single quantum dot transition is simultaneously coupled to two orthogonally pola ...

Two-Color Pump-Probe Measurement of Photonic Quantum Correlations Mediated by a Single Phonon

Vincenzo Savona, Christophe Marcel Georges Galland, Hugo Pierre Alexandre Flayac, Mitchell David Anderson, Kilian Robert Seibold, Santiago Tarrago Velez

We propose and demonstrate a versatile technique to measure the lifetime of the one-phonon Fock state using two-color pump-probe Raman scattering and spectrally resolved, time-correlated photon counting. Following pulsed laser excitation, the n = 1 phonon ...

Exciton-polariton flows in cross-dimensional junctions

Hugo Pierre Alexandre Flayac

We study the nonequilibrium exciton-polariton condensation in 1D to 0D and 1D to quasi-2D junctions by means of non-resonant spectroscopy. The shape of our potential landscape allows to probe the resonant transmission of a propagating condensate between a ...

Multivalley engineering in semiconductor microcavities

Hugo Pierre Alexandre Flayac, Timothy Chi Hin Liew

We consider exciton-photon coupling in semiconductor microcavities in which separate periodic potentials have been embedded for excitons and photons. We show theoretically that this system supports degenerate ground-states appearing at non-zero inplane mom ...

Kinetic Monte Carlo approach to nonequilibrium bosonic systems

Timothy Chi Hin Liew, Hugo Pierre Alexandre Flayac

We consider the use of a kinetic Monte Carlo approach for the description of nonequilibrium bosonic systems, taking nonresonantly excited exciton-polariton condensates and bosonic cascade lasers as examples. In the former case, the considered approach allo ...

Unconventional photon blockade

Vincenzo Savona, Hugo Pierre Alexandre Flayac

We review the unconventional photon blockade mechanism. This quantum effect remarkably enables a strongly sub-Poissonian light statistics, even from a system characterized by a weak single-photon nonlinearity. We revisit the past results, which can be inte ...

Nonclassical statistics from a polaritonic Josephson junction

Vincenzo Savona, Hugo Pierre Alexandre Flayac

We theoretically study the emission statistics of a weakly nonlinear photonic dimer during coherent oscillations. We show that the phase and population dynamics allow to periodically meet an optimal squeezing condition resulting in a strongly nonclassical ...
