Controllable non-reciprocal transmission of single photon in Mobius structure

Abstract

We propose a controllable non-reciprocal transmission model. The model consists of a Mobius ring, which is connected with two one-dimensional semi-infinite chains, and with a two-level atom located inside one of the cavities of the Mobius ring. We use the method of Green function to study the transmittance of a single photon through the model. The results show that the non-reciprocal transmission can be achieved in this model and the two-level atom can behave as a quantum switch for the non-reciprocal transport of the single photon. This controllable non-reciprocal transmission model may inspire new quantum non-reciprocal devices.
