Ten times more throughput on optic fibers

Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because ...

Photons a la Mode: Studying light pulses by counting photons

(Phys.org) —The photodetectors in Alan Migdall's lab often see no light at all, and that's a good thing since he and his JQI colleagues perform physics experiments that require very little light, the better to study subtle ...

Magnetisation controlled at picosecond intervals

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material's magnetisation at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from ...

Fast detector for a wide wavelength range

Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects to be observed that ...

A new tool to split X-ray laser pulses

(Phys.org) —A new tool at SLAC's Linac Coherent Light Source splits individual X-ray laser pulses into two pulses that can hit a target one right after another with precisely controlled timing, allowing scientists to trigger ...

Physicists freeze motion of light for a minute

Physicists in Darmstadt have been able to stop something that has the greatest possible speed and that never really stops. We're talking about light. Already a decade ago, physicists stopped it very for a short moment. In ...
