The versatility of quantum gas experiments greatly benefits from the ability to apply variable potentials. Here we describe a method which allows the preparation of potential structures for microcavity photons via spatially selective deformation of optical resonator geometries with a heat induced mirror surface microstructuring technique. We investigate the thermalization of a two-dimensional photon gas in a dye-filled microcavity composed of the custom surface-structured mirrors at wavelength… Expand

Bespoke mirror fabrication for quantum simulation with light in open-access microcavities.
TLDR
This work uses focused ion beam (FIB) milling to generate custom mirror shapes for quantum simulation in optical microcavities, and shows thermalised light in flat 2D potentials close to dye resonance, and spectrally-resolved cavity modes at the predicted frequencies for elliptical potentials.

Steady-state superfluidity of light in a tunable cavity at room temperature.
Light in a nonlinear cavity is expected to flow without friction -- like a superfluid -- under certain conditions. Until now, part-light part-matter (i.e., polariton) superfluids have been observedExpand
Controllable Josephson junction for photon Bose-Einstein condensates
Josephson junctions are the basis for the most sensitive magnetic flux detectors, the definition of the unit volt by the Josephson voltage standard, and superconducting digital and quantum computing.Expand
Modified Bose-Einstein condensation in an optical quantum gas
TLDR
This work investigates the Bose-Einstein condensation of a photonic Bose gas in an environment with controlled dissipation and feedback and shows that by adjusting their frequency Bose and Einstein condensates naturally try to avoid particle loss and destructive interference in their environment.

Dispersive and dissipative coupling of photon Bose-Einstein condensates
The synchronization of coherent states of light has long been an important subject of basic research and technology. Recently, a new concept for analog computers has emerged where thisExpand
