Optical chirality from dark-field illumination of planar plasmonic nanostructures
Yongsop Hwang, Ben Hopkins, Dapeng Wang +4
Dark-field illumination is shown to make planar chiral nanoparticle arrangements exhibit circular dichroism in extinction analogous to true chiral scatterers. Circular dichrosim is…
Plasmonic edge states: an electrostatic eigenmode description
Daniel E. Gomez, Yongsop Hwang, Jiao Lin +2
We consider periodic arrangements of metal nanostructures and study the effect of periodicity on the localised surface plasmon resonance of the structures within an electrostatic e…
Label-free three-dimensional (3D) structural imaging in live cells using intrinsic optical refractive index
Chen Liu, Michael Malek, Ivan K. H. Poon +10
Here we report a method for visualization of volumetric structural information of live biological samples with no exogenous contrast agents. The process is made possible through a…
Active sorting of orbital angular momentum states of light with cascaded tunable resonators
Shibiao Wei, Stuart K. Earl, Xiao-Cong Yuan +2
Light carrying orbital angular momentum (OAM) has been shown to be of use in a disparate range of fields ranging from astronomy to optical trapping, and as a promising new dimensio…
Diffraction-Free Bloch Surface Waves
Ruxue Wang, Yong Wang, Douguo Zhang +11
In this letter, we demonstrate a novel diffraction-free Bloch surface wave (DF-BSW) sustained on all-dielectric multilayers that does not diffract after being passed through three…
