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…
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…
