Tiny component for record-breaking bandwidth
A modulator developed by researchers from ETH Zurich has broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into the fibre-optic network in a short space of time.

The modulator (in gold) transfers the information from an electrical wave to an optical one. (Illustration: Johannes Grewer / Polariton Technologies).
