High-frequency signal conversion Researchers from ETH Zurich developed a plasmonic modulator capable of converting electrical signals into optical signals with a frequency of over a terahertz. The modulator is a tiny nanostructure made up of various materials, including gold, and makes use of the interaction between light and free electrons within the gold. It converts signals directly, red... » read more
