Researchers from the Moscow Institute of Physics and Technology (MIPT) have for the first time experimentally demonstrated that copper nanophotonic components can operate successfully in photonic devices – it was previously believed that only gold and silver components could do so. Copper components are not only just as good as components based on noble metals; they can also be easily implemented in integrated circuits using industry-standard fabrication processes. "This is a kind of revolution – using copper will solve one of the main problems in nanophotonics," say the authors of the paper. The results have been published in the scientific journal Nano Letters.
