Time-asymmetric loop around an exceptional point over the full optical communications band, Published online: 17 September 2018; doi:10.1038/s41586-018-0523-2

Time-asymmetric light transmission over the entire optical communications band is achieved using a silicon photonic structure with photonic modes that dynamically encircle an exceptional point in the optical domain.
