If you’re keeping the lights on in your enterprise, you’ll want to keep an eye on a new, light-based engineering breakthrough IBM today announced.

The field is nanophotonics. IBM today announced that it has for the first time verified the technology in a manufacturing scenario. Future tech utilizing nanophotonics will be silicon chips that use light instead of or in addition to electrical signals.
Computers using such tech will, IBM reps say, allow data to move more quickly in not just servers equipped with silicon-based nanophotonic chips, but also in systems via data centers — and in supercomputers, too.

The most interesting thing about this announcement is that the tech will work in the standard 90 nanometer semiconductor form factor.

In a statement, IBM Research division director and senior vice president John Kelley said, “This technology breakthrough is a result of more than a decade of pioneering research.” Click here for a white paper that gets into the tech in depth and explains why pulses of light will speed data transfer speeds and how that will affect your enterprise.

This is a breakthrough not only because the technology demonstrably works, he added, but because it allows such optical components  (or silicon nanophotonic) components as modulators and photodetectors to work side by side and in concert with traditional chip tech — and to be manufactured in traditional chip fabs and form factors. Bottom line:

Nanophotonics, long predicted, is closer and now, ostensibly, cheaper to produce than most futurists have been predicting. We’ll be watching with more analysis.

In the meantime, check out this cross section of a silicon-based nanophotonic part that IBM provided this morning.
