The dark side of photonics
Gold heptamer structures show strong Fano resonances. The gold nanoparticles are only about 150 nanometers in diameter. (c) Sven Hein, Na Liu, Harald Giessen, University of Stuttgart, Germany....

What are the realistic promises of metamaterials and cloaking?
Metamaterials are very exciting structures, one of the most exciting areas in photonics, I think. That’s because they allow an almost arbitrary modification of light (or acoustic) waves propagating...

Light-bending to the extreme
Credit: Yushin Kim, Korea Advanced Institute of Science and Technology How does a lens work? Well, as the light arrives at the lens it gets bent towards the focal point of the lens. The denser the lens...

The cloak that hides events in time
The temporal cloak. A light beam of a single colour is directed at a split-time lens (STL) that converts it into different colours. As the beam then propagates through an optical fibre, the blue light...

The ultimate optical surface devices
Metals appear colourful by depositing an ultrathin layer of a semiconductor on top. Shown here is the example of thin germanium films on top of gold. Reprinted by permission from Macmillan Publishers...
