The University of Colorado Boulder in collaboration with the University of California, Berkeley and MIT have successfully developed the first photonic microprocessor.
Why should anyone care? According to Milos Popovic, an assistant professor at Boulder the new processors that come from his technology use light to send signals and information between parts of the processor allowing parts to be smaller than 1 Micron providing bandwidth 10 to 50 times greater than current processors. The results of this are a significantly smaller processor that is faster and more power efficient.
While such technology is still years away from the consumer level, we can already see a glimpse of the processing future.
