Giant bias-free nonreciprocity for unpolarized light via synthetic motion
L. M. Máñez-Espina, B. Amrahi, I. Faniayeu +4
Reciprocity breaking at optical frequencies typically relies on bulky magnets, dynamic modulation, or nonlinearities, all of which hinder chip-scale integration and the handling of…
Realization of the Tellegen Effect in Resonant Optical Metasurfaces
Shadi Safaei Jazi, Ihar Faniayeu, Rafael Cichelero +5
The nonreciprocal magnetoelectric effect in Tellegen materials enables exotic phenomena such as axion-modified electrodynamics and fosters the development of magnet-free nonrecipro…
Optical Tellegen metamaterial with spontaneous magnetization
S. S. Jazi, I. Faniayeu, R. Cichelero +5
The nonreciprocal magnetoelectric effect, also known as the Tellegen effect, promises a number of groundbreaking phenomena connected to fundamental (e.g., electrodynamics of axion…
Extreme nonreciprocity in metasurfaces based on bound states in the continuum
Luis Manuel Máñez-Espina, Ihar Faniayeu, Viktar Asadchy +1
Nonreciprocal devices, including optical isolators, phase shifters, and amplifiers, are pivotal for advanced optical systems. However, exploiting natural materials is challenging d…
Nanoscale optical nonreciprocity with nonlinear metasurfaces
Aditya Tripathi, Chibuzor Fabian Ugwu, Viktar S. Asadchy +6
Optical nonreciprocity is manifested as a difference in the transmission of light for the opposite directions of excitation. Nonreciprocal optics is traditionally realized with rel…
Nanoscale engineering of optical strong coupling inside metals
Artyom Assadillayev, Ihar Faniayeu, Alexandre Dmitriev +1
Optical polaritons appear when a material excitation strongly couples to the optical mode. Such strong coupling between molecular transitions and optical cavities results in far-re…
Macroscopic Magneto-Chiroptical Metasurfaces
Gaia Petrucci, Alessio Gabbani, Esteban Pedrueza-Villalmanzo +4
Nanophotonic chiral antennas exhibit orders of magnitude higher circular dichroism (CD) compared to molecular systems. Merging magnetism and structural chirality at the nanometric…
Broadband reflectionless metasheets: Frequency-selective transmission and perfect absorption
V. S. Asadchy, I. A. Faniayeu, Y. Ra'di +3
Energy of propagating electromagnetic waves can be fully absorbed in a thin lossy layer, but only in a narrow frequency band, as follows from the causality principle. On the other…
