Plasmonic nanostructures can be used to generate optical vortices with varying amounts of angular momentum.

Experiment and theory combine to give a more complete picture of a fundamental problem in diffraction optics.

A device based on photonic crystals exhibits strong optomechanical coupling.

The response of nanostructured metal strips to an electromagnetic field may turn out to be similar to that of atomic gases. Periodic arrays of these artificial metal “molecules” could in principle form a metamaterial that slows light pulses and is easily integrated into optical circuits.

Single photon emission is normally only observed in systems, such as atoms, that are quantum confined in all directions. Now, scientists have shown that carbon nanotubes, which are quasi-one-dimensional materials, can also act as single photon emitters.
