Abstract
Optical non-reciprocity for weak light field is particularly important for chip-based photonic and quantum information process. By adopting the strong nonlinearity associated with a few atoms in a strongly coupled cavity QED system and an asymmetric cavity configuration, we experimentally demonstrate the nonreciprocal transmission between two counterpropagating light fields with extremely low power. The system can be further manipulated to realize a non-reciprocal cavity polariton. Such that an optical isolation exceeds 30dB on single-quanta level and non-reciprocal non-classical statistics with coherent probe lights can be obtained, manifesting the quantum nature of the non-reciprocal polaritons.
