Asymmetric imaging: Reciprocity bounds and manifestations
Romil Audhkhasi, Anna Wirth-Singh, Rose Johnson +6
Recent demonstrations of unidirectional imaging using diffractive multilayers have brought a concept akin to optical isolation to imaging, yet the fundamental limits of such asymme…
Asymmetric Negative Refraction in Nonlocal Double-Wire Metamaterials
Tiago A. Morgado, Sylvain Lannebère, Enrico M. Renzi +2
We demonstrate that heterogeneous double-wire metamaterials, comprising two dissimilar and nonconnected wire arrays, enable loss-asymmetric hyperbolic dispersion and strongly asymm…
Aperiodic temporal modulation for distortionless broadband impedance matching beyond the Bode-Fano limit
Martin Olguin-Lopez, Dimitrios L. Sounas, Nader Engheta +2
The Bode-Fano bound sets a fundamental trade-off between bandwidth and reflection in passive, linear, time-invariant matching networks. We show that an aperiodically time-modulated…
Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-Domínguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
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…
