Review paper on new perspectices on materials for exciton-polritons

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.

Observation of a nonlinearity in Rydberg polaritons in Cu2O.

Synthetic cuprous oxide films have been grown and shown to host Rydberg excitons.

Laser ablation of micron-size parabolic mirrors on glass, and using it for trapping of particles

Observation of a quantised oscillating nonlinear quantum fluid in 1D and 2D potentials in an organic microcavity at room temperature, achieved by an on-the-fly fully tuneable optical approach.

Strong coupling of light to Cu2O Rydberg excitons up to n = 6 and demonstrate the formation of Cu2O Rydberg exciton–polaritons, by embedding a thin Cu2O crystal into a Fabry–Pérot microcavity.
