Synchronous control of dual-channel all-optical multi-state switching
Jiteng Sheng, Junfeng Wang, Min Xiao
We have experimentally observed optical multistabilities (OMs) simultaneously on both the signal and generated Stokes fields in an optical ring cavity with a coherently-prepared mu…
PT-symmetric optical potentials in a coherent atomic medium
Jiteng Sheng, Mohammad-Ali Miri, Demetrios N. Christodoulides +1
We demonstrate that a coherently-prepared four-level atomic medium can provide a versatile platform for realizing parity-time (PT) symmetric optical potentials. Different types of…
Entangler via Electromagnetically Induced Transparency with Atomic Ensembles
Xihua Yang, Yuanyuan Zhou, Min Xiao
We present an efficient and convenient scheme to entangle multiple optical fields via electromagnetically induced transparency in an atomic ensemble. The atomic spin wave, produced…
Spatial-domain interactions between ultra-weak optical beams
Utsab Khadka, Jiteng Sheng, Min Xiao
We have observed the spatial interactions between two ultra-weak optical beams that are initially collinear and non-overlapping. The weak beams are steered towards each other by a…
