Photonic technology can now be used to construct miniature sources of high-frequency radio waves that have exceptional spectral purity. In the early 1980s, researchers at NASA's Jet Propulsion ...

Photonic crystal devices can therefore force light around sharp bands or even trap it entirely. Here the authors develop large-scale nanomaterials to improve the performances of laser propulsion ...

Researchers at the University of Twente, in collaboration with the City University of Hong Kong, have designed a cutting-edge ...
