Photonic Processor: light communications, 50 times faster than the current CPU

Researchers from three US universities developed an information using light instead of electricity transmission microprocessor chip, bandwidth density per square millimeter area of ​​the transmission capacity of 300Gb per second line is currently using only the power of mainstream micro 10-50 times as much as the processor, and more power; which if a microprocessor chip into commercial applications, will be expected to significantly enhance the computing speed computers and network equipment.

There are 70 million transistors and 850 processor photonic circuits within Fengyun photon. The research project moderator, UC Berkeley Associate Professor, Department of Electrical and Computing Vladimir Stojanović said this is the first to take advantage of the light and the world of external communications processor. The researchers also practical to create a special computer, use this to simulate photonic processor.

The study by the University of Colorado campus Bode, UC Berkeley and the Massachusetts Institute of Technology research scholars to participate, published in the 23rd issue of the journal Nature.

Wafer using conventional microprocessor circuitry to transmit information, but with the increase in transmission speed and data volume required of traditional circuit-based microprocessor chip power surge, gradually facing development bottlenecks, and the use of light for communications based optical computing is seen as a new opportunity for a breakthrough in processor technology. Because in the case of using the same power conditions, the light can be transmitted through the medium of distance is far more than even electricity.

Assistant Professor Bode Angeles motor Computing & Energy Engineering, University of Colorado, Miloš Popović said light-based transmission of light through different colors can be on the same wafer, simultaneously transmit different data streams, used in the study of less than 1 micron wavelength beam, thinner than one hundredth of a human hair, it is possible to substantially increase the density of the optical transmission on a single wafer, and thus improve the data transfer bandwidth.

The project has spawned two new companies, researchers are studying how the production process through the existing microprocessor and materials to build a new processor chip, reducing the mass production bottleneck.
