Extremely broadband, on-chip optical nonreciprocity enabled by mimicking nonlinear anti-adiabatic quantum jumps near exceptional points
Nonreciprocal optical devices can be designed based on symmetry breaking at singular points associated with non-Hermitian physics. Here, Choiet al. theoretically show that encircling of exceptional points enables the broadband operation and chip integration of such devices.
