We introduce a unique scheme to investigate topological behavior, using optical-passive elements and Kerr nonlinearities. Compared with previous proposals, the topological band gaps are dramatically broadened, leading to very robust edge modes. Our setup displays intriguing phenomena in the nonlinear regime, including instabilities and the production of squeezed light in the edge modes. This proposal promises unique avenues for engineering phases of light with topological character.
