Magnetic-free nonreciprocal photonic platform based on time-modulated graphene capacitors
TL;DR: In this paper, the authors proposed a framework for the realization of non-reciprocal photonic devices based on time-modulated graphene capacitors coupled to photonic waveguides, without relying on magneto-optic effects.

Fundamentals of optical non-reciprocity based on optomechanical coupling
TL;DR: In this paper, the authors established a unified theoretical framework to analyze optical non-reciprocity and the breaking of time-reversal symmetry in multimode optomechanical systems.

Effects of size and frequency dispersion in plasmonic cloaking
TL;DR: The plasmonic venue to realize invisibility and cloaking is analyzed here in terms of its limitations and its frequency dispersion relative to the cloak size, suggesting potential applications in scattering reduction and noninvasive probing.

- 20 Jan 2021
TL;DR: In this paper, the authors investigate the use of temporal switching to reduce signal reflections from a thin grounded slab over broader bandwidths, and develop an ab initio formalism that can model a broad class of time-switched structures.

Fast encirclement of an exceptional point for highly efficient and compact chiral mode converters
TL;DR: In this article , fast parametric evolution along the parameter space boundary of the system Hamiltonian can relax this constraint, enabling highly efficient transmission and more compact footprint for asymmetric mode converters.
