Photonic Terahertz Phased Array
Li Niu, Xi Feng, Xueqian Zhang +11
Phased arrays are crucial in various technologies, such as radar and wireless communications, due to their ability to precisely control and steer electromagnetic waves. This precis…
Electrodynamics of Photonic Temporal Interfaces
Emanuele Galiffi, Diego Martinez Solís, 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…
Nonlocal phase-change metaoptics for reconfigurable nonvolatile image processing
Guoce Yang, Mengyun Wang, June Sang Lee +10
The next generation of smart imaging and vision systems will require compact and tunable optical computing hardware to perform high-speed and low-power image processing. These requ…
Topological Edge State Nucleation in Frequency Space and its Realization with Floquet Electrical Circuits
Alexander Stegmaier, Alexander Fritzsche, Riccardo Sorbello +11
We build Floquet-driven capactive circuit networks to realize topological states of matter in the frequency domain. We find the Floquet circuit network equations of motion to revea…
