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.…
