December 6, 2007 IBM scientists have announced a breakthrough that could lead to a new generation of supercomputers that squeeze the processing power of today's giants into the form factor of a laptop. The research is based on the use of a light pulses sent through silicon instead of electrical signals on wires which make up conventional computer chips and also promises incredibly energy efficient processors that would expend only the energy of a light bulb to achieve what current supercomputers do with enough power to run hundreds of homes.

The paper, published in the journal Optics Express, concerns the silicon Mach-Zehnder electro-optic modulator - a device which converts electrical signals into pulses of light and promises to significantly reduce cost, energy and heat while increasing communications bandwidth between the cores by a factor of more than 100 over wired chips. The new modulator, which according to IBM is 100 to 1,000 times smaller in size compared to previously demonstrated devices of its kind, acts as a very fast “shutter” to modulate the intensity of the input laser beam and converts a stream of digital bits (“1”s and “0”s) from electrical signals into light pulses.

“Work is underway within IBM and in the industry to pack many more computing cores on a single chip, but today’s on-chip communications technology would overheat and be far too slow to handle that increase in workload,” said Dr. T.C. Chen, vice president, Science and Technology, IBM Research. “What we have done is a significant step toward building a vastly smaller and more power-efficient way to connect those cores, in a way that nobody has done before.”

IBM explain the potential of the technology in terms of the current processor which powers the Sony Playstation 3 - while this contains nine cores on a single chip, the new technology aims to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them.

“We believe this is a major advancement in the field of on-chip silicon nanophotonics,” said Dr. Will Green, the lead IBM scientist on the project. “Just like fiber optic networks have enabled the rapid expansion of the Internet by enabling users to exchange huge amounts of data from anywhere in the world, IBM’s technology is bringing similar capabilities to the computer chip.”

The report on this work, entitled “Ultra-compact, low RF power, 10 Gb/s silicon Mach-Zehnder modulator” by William M. J. Green, Michael J. Rooks, Lidija Sekaric, and Yurii A. Vlasov of IBM’s T.J.WatsonResearch Center in Yorktown Heights, N.Y. is published in Volume 15 of the journal Optics Express and was supported by the Defense Advanced Research Projects Agency (DARPA) through the Defense Sciences Office program “Slowing, Storing and Processing Light”.

Whenever you think you have achieved the height of mans technology just remember...the guy who built the first steam engine thought the same thing.

We wouldn't even recognize the technology that will be common place a century from now. Shit, make that a quarter-century. Look at where its come since the first Apple Macintosh computer (less then 25 years ago)!

:awesome:
Next semester Im going to be doing some all-optical processing research.  Ideally I want to start my own project, but I'm not sure they do that for a masters student that might have to wait till the PhD.  Maybe with a fellowship though?  I don't know the details.  Anyways I realized why a PhD is useful.  It costs nothing, and you get years of expensive ass research for free.  So if one wants to start a business afterwards, all the groundwork has been set for free.

i found an article not too long ago about a processor that had reached 350ghz through current design....though it involved liquid nitrogen...

Intersting article. I figured optics would be the next big thing in CPU's.

I'm just waiting for the new Octo-Core CPU at 5 GHz to come out.
Then I can run Folding@Home on a couple of the cores, and use the remaining six cores for fun stuff.

Something like that would probably require a liquid-nitrogen cooler unit. It may be worth it.
