Transmission Nonreciprocity in a Mutually Coupled Circulating Structure
Bing He, Liu Yang, Xiaoshun Jiang +1
Breaking Lorentz reciprocity was believed to be a prerequisite for nonreciprocal transmissions of light fields, so the possibility of nonreciprocity by linear optical systems was m…
Parity-time-symmetric optical lattice with alternating gain and loss atomic configurations
Zhaoyang Zhang, Liu Yang, Jingliang Feng +4
Since the spatially extended periodic parity-time (PT) symmetric potential can possess certain unique properties compared to a single PT cell (with only a pair of coupled gain-loss…
Observation of Parity-Time Symmetry in Optically Induced Atomic Lattices
Zhaoyang Zhang, Yiqi Zhang, Jiteng Sheng +6
We experimentally demonstrate PT-symmetric optical lattices with periodical gain and loss profiles in a coherently-prepared four-level N-type atomic system. By appropriately tuning…
