The ability to efficiently transfer photons from a light source to an optical circuit is crucial, and requires efficient coupling of light to optical fibres and waveguides. Using state-of-the-art fabrication techniques, Hong-Gyu Park and colleagues create a device that uses nanowires to inject light into photonic-crystal waveguides in an efficient way. The structure could become an important part of the nanophotonics toolbox.
