Description

Following the observation of Bose-Einstein condensation of cavity exciton-polaritons, important advances have been obtained towards the realization of polariton-condensates based devices. I will present, as an example, the realization of an all-optical device controlling polariton condensates in confined geometries, demonstrating the realization of a novel transistor switche mediated by propagating Bose-Einstein polariton condensates in a quasi-1D semiconductor microcavity ridge.
These systems also provide an unparalleled scenario to study fundamental quantum mechanical questions as, for example, those related with the coherence of condensates.
