Bianisotropic metasurfaces empower planarized optical components with subwavelength thicknesses
that are not amenable to conventional optics. In particular, bianisotropy gives control over the
spatial dispersion and allows engineering of both spectral and ...
Low-power and compact phase shifters are crucial for large photonic circuits, both to cope with variability and to create programmable waveguide circuits scaling to thousands of tuning elements. This work demonstrates a liquid crystal phase shifter where a ...
We report on ultrafast transient absorption (TA) studies of surface plasmon-excited similar to 25 nm-diameter Au nanoparticles in solution, monitoring the response of the surface plasmon resonance in the visible region (1.7-3.0 eV) and that of the inter- a ...
Eigenmodes are central to the study of resonant phenomena in all areas of physics.
However, their use in nano-optics seems to have been hindered and delayed for various
reasons. First, due to their small size, the response of nanostructures to a far-field
...
