New Device Could Contribute To A Major Increase In The Rate Of Future Optical Communications
2013-01-08 20:58:34

Harvard School of Engineering and Applied Sciences At a time when communication networks are scrambling for ways to transmit more data over limited bandwidth, a type of twisted light wave is gaining new attention. Called an optical vortex or vortex beam, this complex beam resembles a corkscrew, with waves that rotate as they travel. Now, applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created a new device that enables a conventional optical...
