Researchers show that thin films containing HgTe quantum dots with diameters of around 10 nm exhibit a photoresponse in the mid-infrared that extends to wavelengths as long as 5 µm. Such films could become the basis of a new form of low-cost mid-infrared photodetector.

Researchers have fired ultracold-atom Bose–Einstein condensates towards the submicrometre-featured potentials formed by the optical near-fields of surface plasmons. The strength and structural dependence of the optical near-fields were determined from the reflection of cold atoms. It is hoped that the work paves the way towards plasmonic guiding and the manipulation of cold atoms.

Researchers experimentally demonstrate that light propagating through a path-averaged zero-index dielectric medium can have zero phase delay, despite a non-zero physical path length. The medium is a superlattice consisting of layers of negative-refractive-index dielectric photonic crystals and positive-refractive-index homogeneous dielectric media.
