Advanced Photonics Lab

We are interested in the study of polariton quantum fluids of light, the investigation of frontier physics mainly related to the interactions and coupling of light with matter both from a macroscopic point of view as well as at the single particle level. We study collective coherent phenomena of condensates of Bose-Einstein in semiconductor materials, exploiting quasiparticles generated by the strong coupling between light and excited states of matter. A rich phenomenology of quantum fluids under superfluid or supersonic regimes unravels, involving the dynamics of vortex states, optically driven non-equilibrium condensates, and the expansion or trapping of quantum gases. We measure correlations of quantum states, and highly confined plasmon-polariton fields. We investigate inorganic semiconductors and organic materials from a fundamental point of view as well as for new applied concepts, like all-optical transistors, switches and logical gates.
