Query: Realizing arbitrary trapping potentials for light via direct laser
  writing of mirror surface profiles   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-scale separation. Specifically, we
describe measurements of the spatial redistribution of thermal photons in a
coupled double-ridge structure, where photons form a Bose-Einstein condensate
in a spatially split ground state, as a function of different pumping
geometries.
