Optoelectronics without glass

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 ...

Electro-optical switch transmits data at record-low temperatures

A silicon optical switch newly developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device could enable data transmission ...

New material helps record data with light

Russian physicists with their colleagues from Europe have learned to generate quasiparticles—excitons, which were fully controllable and able to record information at room temperature. These particles act as a transitional ...

Making the switch to polarization diversity

Vast amounts of data transmit across the Internet and telecommunications networks delivering, for example, real-time video calls from one cell phone to another - across the world. As people send and receive increasing amounts ...
