On the physics of multimode polaritons
This thesis is devoted to the study of microcavity polariton systems, in which the strong coupling occurs between more than one exciton or photon modes i.e. multimode polaritons. The first part of this work states the theoretical background of light-matter ...
EPFL2017On the physics of polariton interactions
An exciton-polariton is a quasi-particle that emerges from the strong coupling between an exciton and a photon. Recently, the studies of the exciton-polariton have been receiving a great deal of attention in terms of both fundamental physics and potential ...
EPFL2016Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities
Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi, Souvik Biswas
The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation of single polariton branches, we investigate the different dephasing mechanis ...
Amer Physical Soc2016Noise-Induced Phenomena in Collective Spinor Polariton Excitations
Polaritons are quasiparticles resulting from the strong coupling between photons and excitons embedded in a semiconductor microcavity. The exciton component of polaritons provides strong nonlinear interactions, while their photonic counterpart facilitates ...
EPFL2015Magnetic field tuning of exciton-polaritons in a semiconductor microcavity
Benoît Marie Joseph Deveaud, François Morier-Genoud, Barbara Pietka
We detail the influence of a magnetic field on exciton-polaritons inside a semiconductor microcavity. Magnetic field can be used as a tuning parameter for exciton and photon resonances. We discuss the change of the exciton energy, the oscillator strength, ...
American Physical Society2015Temporally resolved second-order photon correlations of exciton-polariton Bose-Einstein condensate formation
Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Mitchell David Anderson, Hadis Abbaspour, Albert Adiyatullin
Second-order time correlation measurements with a temporal resolution better than 3 ps were performed on a CdTe microcavity where spontaneous Bose-Einstein condensation is observed. After the laser pulse, the nonresonantly excited thermal polariton populat ...
American Institute of Physics2015Heterodyne spectroscopy of polariton spinor interactions
Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Stéphane Trebaol, Naotomo Takemura
We report on spinor polariton interactions in GaAs based microcavities. This investigation is carried out by means of heterodyne polarized pump-probe spectroscopy. We show the dependence of the energy renormalization of the lower and upper polariton resona ...
American Physical Society2014Polaritonic Feshbach resonance
Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Stéphane Trebaol, Naotomo Takemura
A Feshbach resonance occurs when the energy of two interacting free particles comes into resonance with a molecular bound state. When approaching this resonance, marked changes in the interaction strength between the particles can arise. Feshbach resonance ...
Nature Publishing Group2014Influence of a nonradiative reservoir on polariton spin multistability
Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Taofiq Paraïso, Roland Cerna
In this work, we study the influence of the excitation conditions on power-dependent spin switching and spin multistability of exciton polaritons in planar semiconductor microcavities. We obtain experimental evidence for the influence of a reservoir of non ...
American Physical Society2013Build up of off-diagonal long-range order in microcavity exciton-polaritons across the parametric threshold
We report an experimental study of the spontaneous spatial and temporal coherence of polariton condensates generated in the optical parametric oscillator configuration, below and at the parametric threshold, and as a function of condensate area. Above the ...
