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…
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…
