In this work we present the modelling and the experimental results about a new configuration for a non-Hermitian gyroscope, based on dissipative coupling between two modes of an optical resonator. The presence of a Bragggrating in the feeding bus of an optical resonator realizes the dissipative coupling between the counterpropagating modes of a single resonator. This enables the possibility of realizing the anti-PT-symmetric Hamiltonian. Moreover, we demonstrated that this dissipative coupling mechanism can give rise to asymmetric Fano resonant line shapes.

Abstract
In this work we present the modelling and the experimental results about a new configuration for a non-Hermitian gyroscope, based on dissipative coupling between two modes of an optical resonator. The presence of a Bragggrating in the feeding bus of an optical resonator realizes the dissipative coupling between the counterpropagating modes of a single resonator. This enables the possibility of realizing the anti-PT-symmetric Hamiltonian. Moreover, we demonstrated that this dissipative coupling mechanism can give rise to asymmetric Fano resonant line shapes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
