Optoelectronics without glass

Optoelectronics without glass

Microscopic image of a chip. Top left: functional modulator with electrical contacts; right: test modulator without electrical contact; below: test components. Researchers at ETH Zurich have developed the first opto-electronic circuit component that works without glass and is instead made of metal. The component, referred to as a modulator, converts electrical data signals into optical […]

Switching light with a silver atom

Switching light with a silver atom

The switch is based on the voltage-induced displacement of one or more silver atoms in the narrow gap between a silver and a platinum plate. Researchers working under Juerg Leuthold, Professor of Photonics and Communications, have created the world’s smallest integrated optical switch. Applying a small voltage causes an atom to relocate, turning the switch […]
