Breakthrough research to revolutionise internet communication

A team of University of Otago/Dodd-Walls Centre scientists have created a novel device that could enable the next generation of faster, more energy efficient internet. Their breakthrough results have been published in the ...

Spin lasers facilitate rapid data transfer

Engineers at Ruhr-Universität Bochum have developed a novel concept for rapid data transfer via optical fibre cables. In current systems, a laser transmits light signals through the cables and information is coded in the ...

'Astrocomb' opens new horizons for planet-hunting telescope

The hunt for Earth-like planets, and perhaps extraterrestrial life, just got more precise, thanks to record-setting starlight measurements made possible by a National Institute of Standards and Technology (NIST) "astrocomb."

Researchers discover anti-laser masquerading as perfect absorber

Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber ...

Novel laser technology for microchip-size chemical sensors

Most lasers emit photons of exactly the same wavelength, producing a single color. However, there are also lasers that consist of many frequencies, with equal intervals in between, as in the teeth of a comb; thus, they are ...

Changing color of light using a spatiotemporal boundary

A KAIST team developed an optical technique to change the color (frequency) of light using a spatiotemporal boundary. The research focuses on realizing a spatiotemporal boundary with a much higher degree of freedom than the ...

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 ...
