Ultrafast Photonic Computing Processor Uses Polarization

Researchers from the University of Oxford have developed a method using the polarization of light to maximize information storage density and computing performance using nanowires. Similar to how different wavelengths of light do not interact with one another — allowing fiber optic cables to carry multiple parallel streams of data — different light polarizations do not interact. Each polarization can be used as an independent information channel, enabling more information to be stored in multiple channels, greatly enhancing information density. A photonic chip developed by the universities of Oxford and Exeter exploits polarization properties to boost performance. Courtesy of June Sang Lee/University of Oxford....
