Fabrication et caractérisation des microcavités à base de ZnO en régime de couplage fort : laser à polaritons by Feng Li( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Cavity polaritons are quasi-particles, partially light partially matter, resulting from the strong-coupling of an exciton and a cavity photon. At a certain temperature and particle density, cavity polaritons can go through a quasi-Bose-Einstein phase transition and condense at the lowest energy state of the system; in this situation the cavity emits coherent light and the associated device is termed polariton laser. ZnO is one of the most adapted materials for fabricating room temperature polariton lasers, due to its excellent excitonic properties. However, technical difficulties have been preventing the achievement of ideal ZnO microcavities for a long time. In this thesis we report the fabrication of high quality ZnO microcavities with two different approaches, which overcome the existing technical challenges and allow to achieve a record cavity quality factor and large Rabi splittings. Room temperature polariton lasing has been demonstrated in both cases. In a fully-hybrid ZnO microcavity, polariton condensates were studied within an unprecedented range of exciton-photon detunings, and from low to room temperature. This tunability has enabled to obtain, for the first time, a complete condensation phase diagram for ZnO-based microcavities, wherein the exciton fraction of the polaritons has been tuned between 17% to 96%, corresponding to a modification of the exciton-polariton mass, its lifetime and its interaction constant by 1 order of magnitude. This thesis paves the way for implementing a polariton-based technology operating at room-temperature
