Intel trumpets optical computing breakthrough

Researchers from Intel and the University of California at Santa Barbara (UCSB) have unveiled a new hybrid silicon laser technology that will allow for faster communications inside a computer.

The researchers succeeded in mixing light-emitting indium phosphide inside a silicon chip through the use of an oxide layer that functions as a 'glass glue'. The indium phosphide is required to power the laser, making a chip's optical component. The new technology enables manufacturing using regular silicon production technologies, making for an inexpensive production process.

So-called photonic chips mark a step forward in the development of semiconductors by allowing them to use optical technology to communicate with other chips and components inside a computer. Replacing current electrical communications using copper wires, photonics offer increased bandwidth to power high speed chips of the future, UCSB professor John Bowers explained in a conference call.

"Electrical communications have a lot of dispersion and require a lot of power. That's a huge problem in the industry today. Optic technology (phonetics) gets around this."

The new hybrid technology that's mixing silicon with phosphide will allow for mass production of the chips, touted Mario Paniccia, director of Intel's Photonics Technology Lab.

"We are now able to start integrating photonics elements to build things that weren't available previously. This bring photonics to the mass market," said Paniccia.

Intel envisions hundreds of the hybrid silicon lasers being placed on a single chip, allowing for what Paniccia calls "a new era of high-performance computing applications."

"You now have the capability to converge communications and computing on one platform. That's extremely powerful," Paniccia said.

While the new process could allow for mass-production of phonetic devices, Intel cautioned that consumer products based on the technology are still years away.

someone has to make the lame joke sooner or later:

"first snakes on a plane......now lasers on a freakin' chip?"

same as fibre optics pretty much. I dont think heat will be a problem,, they wont be strong lasers, not enough to generate any significant heat. Iv been waiting for this for like 3 years.

Once this happens, i wonder if all the different manufacturers will join in. Laser all the way to the vid card,, add a solid state hard drive in there and you are smokin

^ I'm sure Intel is scrambling for that patents...

well i finally read the article and i don't have that much faith in it's accuracy. for one they completely butchered Moore's law. secondly what the heck are they on about when referring to how much cheaper it will be to transfer these optical signals? to transfer the signal from one house to another will still require a fibre optic network and repeaters.

[The General]

Since the size is much smaller, it doesn't need a transfer medium, just a transmitter and receiver, or some tranceivers.

It will save money because we don't need to make thousands of super-microscopic wires anymore.

instead, we need thousands of microscopic lasers, which need to be really accurate...
