The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

open access: yesAdvanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Ellipticity‐Controlled Exceptional Points and Cross‐Polarized Phase Singularities in Multi‐Layer Silicon Guided Mode Resonant Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.

C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination

open access: yesAdvanced Optical Materials, EarlyView.
This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...
