Holey Optochip: the optical chip from IBM

Data transfer will be by fibre optics, IBM confirmed us!

Optical processors, or simply optical chips, it is neither the first nor the last time that we will hear speak. To summarize, researchers are trying to break out of the transfer of information about copper tracks that travel our maps mothers and other electronic cards to drastically increase the bandwidth. To achieve fiber pathway is preferred because it allows to benefit from the speed of light that physically provides information at speeds of almost unlimited transfer speeds, once used electronics following. On this point, IBM researchers appear to have taken a new step forward.

IBM introduced its Holey Optochip chips with 24 holes for the reception of the signal light and 24 other holes for the issue of information by optical fibre. The transfer rate would be of the order of 1 Tb/s... for a short distance, of course. The consumption of such chip does not exceed 5 Watts, this could be interesting for future major centres of calculations or data centers.

IBM said its show of force that the manufacture of the chip does not use new technologies or methods of complex manufacturing, but components today classics on the market, making it so cheap to produce.

For researchers, the problem of bandwidth between the components of a computer is then more a problem with this type of optical chips. For them, the bottleneck is now moved to bandwidth network, even if the optical fiber in data-center is widely used. He would then produce optical chips more efficient to propel the light signals over a greater distance, increasing the speed of transfer between components and units of calculation then mechanically.

We hope now that this type of demonstration are not made only to show the power and the level of research in the laboratories of IBM, but that this could lead to actual use in our future computers. Finally, this is not to immediately...
