Brussels. An international research group, within the Erasmus Mundus Nanophi project, coordinated by the Department of Information Engineering of the University of Brescia, has found ways to make non-linear optical processes at the nanoscale more efficient, laying the groundwork for the development of a new generation of frequency conversion and nano-laser nano-devices. The research was funded by the Russian Science Foundation and the European Community, while the results were published in the prestigious journal “Physical Review Letters” and made it to the cover story of the July 20th, 2018 edition.
