| description | The strong nonlinearities of exciton-polariton condensates in lattices make
them suitable candidates for neuromorphic computing and physical simula-
tions of complex problems. So far, all room temperature polariton condensate
lattices have been achieved by nanoimprinting microcavities, which by nature
lacks the crucial tunability required for realistic reconfigurable simulators.
Here, we report the 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. Remarkably, the
condensate is delocalised from the excitation region by macroscopic dis-
tances, leading both to longer coherence and a threshold one order of mag-
nitude lower than that with a conventional Gaussian excitation profile. We
observe different mode selection behaviour compared to inorganic materials,
which highlights the anomalous scaling of blueshift with pump intensity and
the presence of sizeable energy-relaxation mechanisms. Our work is a major
step towards a fully tuneable polariton simulator at room temperature. |
