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

Visible Light Silver Nanoantenna on UV Responding Tin Nanoparticles
EUV radiation for lithography is currently produced by a tin particle plasma, ignited by intense laser light in the infra‐red region. Here, tin nanoparticles are designed to absorb visible light with the help of a silver nanoantenna. This visible light capturing potential was confirmed by EELS and STEM, with the surface plasmon resonance of the ...

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...
