Optical Limiter Based on PT-Symmetry Breaking of Reflectionless Modes

F. Riboli, R. Kononchuk, F. Tommasi +8

The application of parity-time (PT) symmetry in optics, especially PT-symmetry breaking, has attracted considerable attention as a novel approach to controlling light propagation.…

Universalities of Asymmetric Transport in Nonlinear Wave Chaotic Systems

Cheng-Zhen Wang, Rodion Kononchuk, Ulrich Kuhl +1

The intrinsic dynamical complexity of classically chaotic systems enforces a universal description of the transport properties of their wave-mechanical analogues. These universal r…

Enhanced Signal-to-Noise Performance of EP-based Electromechanical Accelerometers

Rodion Kononchuk, Jizhe Cai, Fred Ellis +2

Exceptional points (EP) are non-Hermitian spectral degeneracies where both eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted a lot of attentio…

A reflective mm-wave photonic limiter

Rodion Kononchuk, Suwun Suwunnarat, Martin S. Hilario +6

Millimeter wave (mm-wave) communications and radar receivers capable of processing small signals must be protected from high-power signals, which can damage sensitive receiver comp…

Thermal Motors with Enhanced Performance due to Engineered Exceptional Points

Lucas J. Fernández-Alcázar, Rodion Kononchuk, Tsampikos Kottos

A thermal current, generated by a temperature gradient between two reservoirs coupled to a carefully designed photonic or (micro-) electromechanical circuit, might induce non-conse…

Extreme Non-Reciprocal Near-Field Thermal Radiation via Floquet Photonics

Lucas J. Fernández-Alcázar, Huanan Li, Tsampikos Kottos

By utilizing Floquet driving protocols and interlacing them with a judicious reservoir emission engineering we achieve extreme non-reciprocal thermal radiation. We show that the la…

Orientation-sensed Optomechanical Accelerometers based on Exceptional Points

Rodion Kononchuk, Tsampikos Kottos

We propose an optomechanical design, consisting of a parity-time symmetric multilayer structure tuned at exceptional-point degeneracy (EPD), with an adjustable layer that is couple…

Free-Space Wide-Aperture Sheet-Isolator Based on a Multilayered Resonant Cavity

R. Kononchuk, C. Pfeiffer, I. Anisimov +3

We introduce the first conceptual design of a free-space thin-sheet isolator with unlimited aperture and the possibility of a broadband omnidirectional rejection of the backward pr…
