Researchers at CIC nanoGUNE (Basque Country) in collaboration with colleagues at ICFO-The Institute of Photonic Sciences (Catalunya) have imaged how light moves inside an exotic class of matter known as "hyperbolic materials." They observed, for the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride—a natural hyperbolic material for infrared light. This work has been funded by the EC Graphene Flagship and was recently reported in Nature Photonics.
