Light-based computers to be 5,000 times faster

Electrical currents are best created using semiconductor crystals that absorb light, say researchers who have announced a significant, potential computer-speed breakthrough. The team obtained ultrafast clock rates in the terahertz of frequencies, using light. That is significantly higher than existing single-gigahertz computer clock rates.

The “bursts of light contain frequencies that are 5,000 times higher than the highest clock rate of modern computer technology,” researchers at the Forschungsverbund research association in Germany announced in a press release last month. A chip’s oscillating frequencies, called clock rate, is one measurement of speed.
