This month in Tech Briefs: Researchers from the National Institute of Standards and Technology have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second — faster than any other similar device.
The switch is a major step toward building a computer that uses light instead of electricity to process information. Read the Tech Brief.
