  • The Quantum Optoelectronics team at the LPCNO is starting a new experimental activity aimed at exploring exotic states (giant orbitals, called “Rydberg” orbitals) of electron-hole pairs (excitons) in a wide-gap semiconductor 1-2. Rydberg states have remarkable properties such as mesoscopic sizes and long-range giant interactions, which make them prime candidates for solid- state quantum technologies, i.e. realized in a solid structure. We study in particular the possibilities that these states offer for non-linear quantum optics, with a view to developing a new type of quantum sensor.

    The team possesses advanced laser systems (UV, Visible, IR) and sophisticated measuring devices, allowing us to probe various states with great precision. We aim to use different light sources to better understand the giant optical nonlinearities stemming from Rydberg physics 3 and to develop novel two-colors optical control schemes in view of developing solid- state quantum sensors.
