An international research team from Germany, Italy, and the U.K. has developed a key photonics component for the terahertz spectral range. By mixing electronic resonances in semiconductor nanostructures with the photon field of microresonators, they designed a stained mirror that bleaches more easily than ever and could make terahertz lasers ultrafast. The results are published in the current issue of Nature Communications.
