Controlling the transverse flow of light in a high-finesse optical microresonator

Controlling the flow of light is a fundamental requirement for quantum simulations with light. We have recently introduced two novel direct laser writing methods for the microstructuring of mirrors, which allow us to control the transverse flow of light in a high finesse optical microresonator [1]. In particular, it is possible to capture photons onto periodic lattices sites and to control their tunnelling rate. In future work, this will enable...
