Abstract
The non-Hermitian concepts, including PT symmetry-breaking, of judiciously utilizing both optical gain and loss in metaphotonic structures have recently emerged as a new paradigm to control the propagation of light. We present experimental realizations of non-Hermitian dynamics near exceptional points (EPs) both in electric resonators and silicon-photonic waveguides that create dynamically encircling an EP and consequent time-asymmetric transmission of broadband signals.
