Abstract
- We propose a scheme of a topological optical isolator based on the quantum anomalous Hall effect with strongly coupled exciton-polaritons in a patterned GaAs cavity. We study the practical properties of such a device and optimize its parameters. We obtain an isolation ratio of 49 dB at a wavelength of 783 nm for a device of 40 μm with a maximal signal modulation frequency of 300 GHz, operating at temperatures up to 50 K.
