Electrodynamics of Photonic Temporal Interfaces
Emanuele Galiffi, Diego Martinez SolÃs, Shixiong Yin +2
Exotic forms of wave control have been emerging by engineering matter in space and time. In this framework, temporal photonic interfaces, i.e., abrupt changes in the electromagneti…

Optical coherent perfect absorption and amplification in a time-varying medium
Emanuele Galiffi, Anthony C. Harwood, Stefano Vezzoli +3
Time-invariant photonic structures amplify or absorb light based on their intrinsic material gain or loss. The coherent interference of multiple beams in space, e.g., in a resonato…
