New processes push technology to the verge of commercialization
International Business Machines, Inc. (
is among the companies
racing to develop nanophotonics
-- on-die light based signaling components -- which can be incorporated directly side-by-side with traditional silicon-based electronics using traditional manufacturing techniques like complementary metal-oxide semiconductor (CMOS).
Currently, signals between components like the processor cores and the memory crawl along as electrons along copper-based wires. In the new scheme
(which create the signal,
often using a ring
), wave-length multiplexers (which route signals),
(which turn signals on or off), and detectors (which receive signals) are baked onto silicon chips connected by fiber optics. Signals then travel at the speed of light along fiber optic channels.
After first demoing the technology in crude proof-of-concept form back in 2010, IBM has returned with the world's smallest announced CMOS-compatible nanophotonics processes. The company
chips this week that were build on a traditional 90 nm CMOS node, a node far smaller than earlier prototypes.
Blue optical wires are shown accelerting the "slow" copper wire (orange) traffic.
IBM says the technology is "primed for commercial development" and will soon be ferrying "terabytes of data between distant parts of computer systems". In a demo IBM showed off 25 gigabytes-per-second (GBps) transfer rates, a speed typically seen in bulky telecommunications fiber-optics equipment, not in PC interconnects, which crawl along at megabytes-per-second (or around 1 Gbps for high-speed PCI-express lanes).
The hope is that the new interconnects will soon pump internal and external communication up to speeds of up to thousands of times the current technology.
Dr. John E. Kelly, Senior Vice President and Director of IBM Research, remarks, "This [latest showcased] technology breakthrough is a result of more than a decade of pioneering research at IBM. This allows us to move silicon nanophotonics technology into a real-world manufacturing environment that will have impact across a range of applications."
The IBM research fellow and SVP will be showing off his work
in a paper
at the IEEE International Electron Devices Meeting (
), which is being held this week in San Francisco, Calif.

Respectfully disagree. I'm sure that nobody ever thought that consumers would ever need multi-terabyte storage systems, multi-core processors, solid state storage drives, or even portable computers. These days, a company is behind the times if they don't offer it.
The gist is that all technology (even military up to a point) will continue to trickle down into the consumer space given enough time as the technology develops. Eventually it may come down to the point where you slide an expansion card into a bay, and connect an optical cable between it and the processor as it only uses the slot for providing power.
