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 ...

Reservoir-induced decoherence of resonantly excited confined polaritons

Benoît Marie Joseph Deveaud, François Morier-Genoud, Daniel Oberli, Marcia Portella Oberli, Grégory Chilpéric Sallen, Claudéric Ouellet-Plamondon

We report on the effect of decoherence on polariton bistability. The polariton hysteresis loop is shown to collapse in a similar way when increasing the temperature or under nonresonant excitation power. The hysteresis upward threshold is pulled to lower e ...

Spatial multistability induced by cross interactions of confined polariton modes

Benoît Marie Joseph Deveaud, François Morier-Genoud, Daniel Oberli, Marcia Portella Oberli, Grégory Chilpéric Sallen, Claudéric Ouellet-Plamondon

We demonstrate the occurrence of spatial multistability using laterally confined microcavity exciton-polaritons. By coherently exciting with a blue detuned laser a series of confined polariton modes, we investigate the effects of multistability on the tran ...

Multiple polariton modes originating from the coupling of quantum wells in planar microcavity

Benoît Marie Joseph Deveaud, Daniel Oberli, Grégory Chilpéric Sallen, Claudéric Ouellet-Plamondon, Fauzia Jabeen

We report on the observation of multiple polariton modes, originating from an electronic coupling between quantum wells inside a planar microcavity. A series of excitonic transitions are measured for a bare quantum well stack and are precisely identified t ...

Spontaneous self-ordered states of vortex-antivortex pairs in a polariton condensate

Vincenzo Savona, Benoît Marie Joseph Deveaud, Konstantinos Lagoudakis, Timothy Chi Hin Liew, Francesco Manni, Claudéric Ouellet-Plamondon

Polariton condensates have proved to be model systems to investigate topological defects, as they allow for direct and nondestructive imaging of the condensate complex order parameter. The fundamental topological excitations of such systems are quantized v ...
