We present a comprehensive overview of chirality and its optical manifestation in plasmonic
nanosystems and nanostructures. We discuss top-down fabricated structures that range from …

Chirality is a universal geometric property in both micro‐and macroworlds. Recently, optical
chiral effects have drawn increased attention due to their great potential in fundamental …

The optical chirality of metamaterials gives birth to distinct responses of left circularly
polarized (LCP) and right circularly polarized (RCP) light, leading to asymmetric …

Transition metal dichalcogenide (TMDC) monolayers have enabled important applications
in light emitting devices and integrated nanophotonics because of the direct bandgap, spin …

The symmetry dependences of plasmon excitation modes are studied in 3D silver nanorod
trimers. The degenerate plasmon modes split into chiral modes by breaking the inversion …

We propose ultra-broadband reflective and absorptive polarizers in the visible range using
multi-scaled Ag nano wire-slit arrays. The nano arrays can be tuned from reflective to …

We show that broadband optical magnetism can be achieved through incorporating multi-
scaled 3D metallic meta-elements into Z-shaped nanohole arrays. The broadband effect …

We demonstrate large circular dichroism (CD) in the visible range resulting from
electromagnetic couplings in three-dimensional Ag staircase nanostructures. Analytical …

Geometrical chirality in molecules or plasmonic nanostructures can lead to unique optical
responses such as circular dichroism or optical rotatory dispersion. It is important to …

The readily accessible commercial electron beam lithography (EBL) has high-accuracy and
mask-free characteristics which enable fast exploration of novel on-chip devices. However …
