New Optical Computing Approach Offers Ultrafast Processing

Ultrafast computer processing speeds are possible with optical chirality logic gates that operate about a million times faster than existing technologies.

Processing devices based on polarized light run one million times faster than current technology.

Logic gates are the basic building blocks of computer processors. Conventional logic gates are electronic, working by shuffling around electrons. However, researchers have been developing light-based optical logic gates to meet the data processing and transfer demands of next-generation computing. Aalto University scientists developed new optical chirality logic gates that operate about a million times faster than existing technologies, offering ultrafast processing speeds.
