Optics & Photonics
How light is shaped, guided, trapped and measured.
Metasurfaces and metamaterials
- Can a flat lens focus all colours to the same spot?
- Can a flat optic control both brightness and phase of light?
- Can one metasurface store many holograms selected by polarization?
- Can one flat optic control brightness and phase for two polarizations?
- Can one flat lens read both a light beam's spin and its twist?

Plasmonics
- Can a neural network design nanostructures for a chosen color response?
- Can boron nitride antennas amplify molecular infrared signals?
- Can DNA origami be used to print tiny gold antennas?
- Can one nano-hole respond to twist one way and angle the other?
