Coherent electron trajectory control in graphene

Electronic systems using light waves instead of voltage signals is advantageous, as electromagnetic light waves oscillate at petaherz frequency. This means that future computers could operate at speeds 1 million times faster ...

Millimetre waves for the last mile

Reseachers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the "last mile" up to the internet ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Gas-detecting laser device gets an upgrade

University of Michigan researchers have refined a gas-sniffing device so that it can detect poisonous gases and explosives in less than half a second.

'Optical rocket' created with intense laser light

In a recent experiment at the University of Nebraska–Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light.
