Abstract

Chiral light-matter interactions have an extremely weak nature, are difficult to be controlled and enhanced, and cannot be made tunable. Here, we experimentally realize and theoretically verify spectrally tunable, extremely large, and broadband circular dichroism by designing new nanohelical metamaterial configurations (U. Kılıç et. al., Advanced Functional Materials 31(20), 2010329, 2021). The currently presented bottom-up fabricated hybrid helical metamaterials can be used in a plethora of diverse emerging classical and quantum optical applications, such as in the design of ultrathin polarization filters, chiral sensors, circular polarized single- or multi-photon radiation sources, and directional spin-dependent nanophotonic waveguides.
