The processors still use electrical circuits, but the chips convert the electrical information to light pulses, which then transfer between chips.

"Using ultra-short light pulses gives us the ability to focus in a well confined region and the ability for intense radiation, " said Parigger.

We then take hundreds of these narrow videos (each shot at a slightly different angle) and create a carefully synchronized, slow-motion composite of the light pulses.
The computer maker managed to simultaneously transmit 55 wavelengths and came up with a way of amplifying the light signals every 50 kilometers, since light pulses degrade over long stretches and must be strengthened.
The new single-laser fiber-optic speed record was set using a technique called fast Fourier transform that pulses light at an incredibly high rate with data encoded in 325 distinct colors across the spectrum.
The chips use pulses of light to communicate between chips in servers, racks and supercomputers.

But as cells seem to respond most to patterns, the researchers experimented with various pulses of light.
Optogenetics could someday lead to implantable brain devices that correct malfunctioning circuits by zapping them with pulses of light.
Researchers have steadily overcome such challenges to build a series of building blocks from silicon, including components that modulate pulses of light from lasers to encode data and detect such signals.
Sending large amounts of information down an optical fibre is done by encoding many separate streams of data as pulses of light of different colours, so that they can travel along the fibre without interfering with each other.
ECONOMIST: Optical fibres could carry more information in the future
Mapping nearby features, spotting road edges and lane markings, reading signs and traffic lights and identifying pedestrians is done using a combination of cameras, radar and lidar (which works like radar, but with pulses of light rather than radio waves).
The just-unveiled Media Player 7 handles most audio and video formats, is an MP3 jukebox for recording, organizing and playing music, and has enough advanced features to take on the competition - including a 10-band equalizer, a psychedelic light-show that pulses in time to the music, and appearance-changing "skins" that turn the gray box into things like the big green head pictured.
He used photons (in the form of carefully calibrated pulses of laser light) to probe atoms.
They used intense nanosecond pulses of laser light to turn the metal's lustrous surface a deep black.
To measure the energy in question, he used two successive pulses of laser light, each 250 attoseconds long.
Newer developments in laser technology, such as nonablative fractional resurfacing, in which the laser divides the light up into many smaller pulses, have decreased the healing time.
His weapon: a rolling, 3-foot-tall machine (think R2-D2 from Star Wars) called the Xenex that bathes hospital rooms with intense, millisecond pulses of ultraviolet light from a high-wattage strobe light.

Using pulses of laser light aimed through the appropriate microlenses, the researchers were able to set each of the qubits into a particular initial state a necessary precursor to any calculation.
Such snapshots, which are captured by using pulses of laser light a few femtoseconds long rather than by physically clicking a shutter, are able to catch molecules in the process of reacting together.
The cells can then be turned on or off with pulses of blue and yellow light.
The signal preemption idea was born in the early 1970s, when 3M devised a system that let emergency vehicles change traffic signals with pulses of strobe lights (later, infrared light) transmitted to receivers mounted over roadways.
Later this year Dr Tzou hopes to have one that will deliver femtosecond pulses along flexible fibre cables, which can be held like a light-pen.
