Enhanced Diffractive Circular Dichroism from Stereoscopic Plasmonic Molecule Array

Nanomaterials, 2023
Artificial nanostructures with large optical chiral responses have been intensively investigated recently. In this work, we propose a diffractive circular dichroism enhancement technique using stereoscopic plasmonic molecule structures.

Circular dichroism of cholesteric polymers and the orbital angular momentum of light [PDF]

, 2011
We explore experimentally if the light's orbital angular momentum (OAM) interacts with chiral nematic polymer films. Specifically, we measure the circular dichroism of such a material using light beams with different OAM.

Valence Band Circular Dichroism in non-magnetic Ag/Ru(0001) at normal emission [PDF]

, 2013
For the non-magnetic system of Ag films on Ru(0001), we have measured the circular dichroism of photoelectrons emitted along the surface normal, the geometry typically used in photoemission electron microscopy (PEEM).

Dynamic tuning of enhanced intrinsic circular dichroism in plasmonic stereo-metamolecule array with surface lattice resonance

Nanophotonics, 2020
Enhancing the circular dichroism signals of chiral plasmonic nanostructures is vital for realizing miniaturized functional chiroptical devices, such as ultrathin wave plates and high-performance chiral biosensors.

Controlled rotary motion of light-driven molecular motors assembled on a gold film [PDF]

, 2010
Using circular dichroism (CD) spectroscopy, we show that light-driven rotary molecular motors based on overcrowded alkenes can function in a self-assembled monolayer on semi-transparent gold films.

Vibrational circular dichroism unveils hidden clues

Light: Science & Applications, 2023
Infrared chiral plasmonic metamaterials based on perpendicularly positioned nanorods enable surface-enhanced vibrational circular dichroism for more selective and sensitive identification of protein fingerprints and enantioselective sensing, which ...

Optical Spectra and Localization of Excitons in Inhomogeneous Helical Cylindrical Aggregates [PDF]

, 2004
We study the linear optical properties of helical cylindrical molecular aggregates accounting for the effects of static diagonal disorder. Absorption, linear dichroism, and circular dichroism spectra are presented, calculated using brute force numerical ...

Measuring circular phase-dichroism of chiral metasurface

Nanophotonics, 2019
The ability of chiral media to differentiate circularly polarized light is conventionally characterized by circular dichroism (CD) which is based on the difference in the absorption of the incident light for different polarizations.

Magnetic circular dichroism versus orbital magnetization

Physical Review Research, 2020
The magnetic circular dichroism sum rule yields an extremely useful ground-state observable, which provides a quantitative measure of spontaneous time-reversal symmetry breaking (T-breaking) in a given material.
