Title (EN) NON-RECIPROCAL LASING IN TOPOLOGICAL CAVITIES OF ARBITRARY GEOMETRIES
(FR) ÉMISSION LASER NON RÉCIPROQUE DANS DES CAVITÉS TOPOLOGIQUES DE GÉOMÉTRIES ARBITRAIRES
Abstract:
(EN) 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.
(FR) Une source laser comprend une cavité topologique pour une émission laser non réciproque, un matériau magnétique et un guide d'ondes optique. Le matériau magnétique est agencé pour interagir avec la cavité topologique. Le guide d'ondes optique est conçu pour recevoir la lumière extraite de la cavité topologique lors de la rupture de la symétrie par renversement du temps dans la cavité topologique.
