Tiny particles composed of metals and semiconductors could serve as light sources in components of future optical computers, as they are able to precisely localize and extremely amplify incident laser light. A team from Germany and Sweden led by Prof. Dr. Christoph Lienau and Dr. Jin-Hui Zhong from the University of Oldenburg has now explained for the first time how this process works. The study is published in the current issue of the journal Nature Communications.
