Topological effects offer interesting applications in photonic circuits. Ring resonators can be coupled to one another in an 2D array in such a way that they exhibit optical edge states similar to the eletrical edge states in topological insulators. These edge states are protected from pertubations and could be utilized to build all-optical switches with a high integration density. In this scheme an optically excited thermal atomic vapor interacts with the evanescent light field inside the resonators and thus switches the path the light takes through the resonator array.
In this talk our progress towards integrated all-optical switches utilizing topological protection is presented.
