Abstract

See full text

A laser source includes a topological cavity for nonreciprocal lasing, a magnetic material and an optical waveguide. The magnetic material is arranged to interact with the topological cavity. The optical waveguide is arranged to receive light extracted from the topological cavity upon breaking of time-reversal symmetry in the topological cavity.
