The image above shows vortex laser on a chip. Because the laser beam travels in a corkscrew pattern, encoding information into different vortex twists, it’s able to carry 10 times or more the amount of information than that of conventional lasers. Credit: University at Buffalo.
Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion. The optics advancement could become a central component of next generation computers designed to handle society’s growing demand for information sharing. It may also be a salve to those fretting over the predicted end of Moore’s Law, the idea that researchers will find new ways to continue making computers smaller, faster and cheaper.
“To transfer more data while using less energy, we need to rethink what’s inside thes...
