Optical chirality of membrane metasurfaces with broken in-plane symmetry
Ivan Toftul, Brijesh Kumar, Yuri Kivshar
We study chiroptical properties of single-layer dielectric membrane metasurfaces with broken in-plane symmetry. Although chiral optics was long tied to structures lacking any mirro…
Intrinsic chirality of dielectric metasurfaces unlocked by resonant chiral modes
Brijesh Kumar, Pavel Tonkaev, Ivan Toftul +7
Controlling optical chirality at the subwavelength scales is essential for many applications of nanophotonic structures in polarization optics, sensing, and nonlinear photonics. Ac…
Observation of Janus Chirality for Coherent Thermal Emission from Metasurfaces
Kaili Sun, Yangjian Cai, Maxim V. Gorkunov +2
Metasurfaces emerged as a powerful tool for controlling thermal radiation, yet achieving coherent emission with opposite circular handednesses remains a highly challenging problem.…
Maximal optical chirality via mode coupling in bilayer metasurfaces
Brijesh Kumar, Ivan Toftul, Anshuman Kumar +2
Recent advances in the physics of resonant optical metasurfaces allowed to realize the so-called maximum chirality of planar structures by engineering their geometric parameters. H…
Orbital chiral lasing in twisted bilayer metasurfaces
Mingjin Wang, Nianyuan Lv, Zixuan Zhang +11
Chirality is a fundamental concept in physics that underpins various phenomena in nonlinear optics, quantum physics, and topological photonics. Although the spin of a photon natura…
Chiral Nonlinear Polaritonics with van der Waals Metasurfaces
Connor Heimig, Alexander A. Antonov, Dmytro Gryb +10
In the strong-coupling regime, the interaction between light and matter reaches a hybridization state where the photonic and material components are inseparably linked. Using tailo…
Substrate-induced maximum optical chirality of planar dielectric structures
Maxim V. Gorkunov, Alexander A. Antonov, Alena V. Mamonova +2
Resonant dielectric planar structures can interact selectively with light of particular helicity thus providing an attractive platform for chiral flat optics. The absence of mirror…
Chirality tuning and reversing with resonant phase-change metasurfaces
Xinbo Sha, Kang Du, Yixuan Zeng +8
Dynamic control of circular dichroism in photonic structures is critically important for compact spectrometers, stereoscopic displays, and information processing exploiting multipl…
