Oscillation-free unconventional photon blockade from quadrature driving of a Kerr dimer
Driving the two sites of a Kerr dimer in quadrature gives unconventional photon blockade with a smooth, oscillation-free g²(τ) that standard detectors can resolve, at weak nonlinearity and without post-fabrication cavity trimming.

Ultra-small mode volume polariton condensation via precision He+ implantation
Focused He+ ion implantation imprints loss-defined traps directly into GaAs microcavities, confining polariton condensates to a mode volume of only 0.6 μm³ while preserving strong coupling — small enough to support a single condensate mode.

Local tuning of Rydberg exciton energies in nanofabricated Cu2O pillars
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.
