Description

We use tunable cavities with nanoscale defects to create zero-dimensional exciton-polaritons. Data on the strong coupling as well as mode properties are shown as a function of cavity detuning. At ambient conditions, we observe polariton condensation with strong lateral confinement on the wavelength scale.
As a building block towards extended lattices, we realize two coupled cavities by focused ion beam milling and thermal scanning probe lithography. These photonic molecules are investigated by means of atomic force microscopy and optical measurements, to compare both fabrication methods.
These are initial steps towards a quantum simulator with polaritons in arbitrary potential landscapes at ambient conditions.
