  • Cu2O is a promising platform to host Rydberg exciton–polaritons, where excitons strongly couple to cavity photons, however their realization has been elusive. Here, the authors report Rydberg exciton–polaritons with principal quantum numbers up to n = 6.

  • Rydberg excitons in cuprous oxide feature giant optical nonlinearities that may be exploited in quantum applications if suitably confined. Here, the authors show how exciton confinement can be realised by focused-ion-beam etching of Cu2O crystals without noticeable degradation of excitonic properties.

  • Strong effective photon–photon interactions (Kerr-like optical nonlinearity) via the Rydberg blockade phenomenon in Cu2O-microcavity achieved under pulsed resonant excitation enabling fundamental studies of strongly correlated polaritonic states and quantum optical applications.
