Vortex laser encodes 10 times more data

Researchers are pushing laser technology forward using another light manipulation technique called orbital angular momentum, which distributes the laser in a corkscrew pattern with a vortex at the center.

Usually too large to work on today’s computers, the UB-led team was able to shrink the vortex laser to the point where it is compatible with computer chips. 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, which move linearly.

The vortex laser is one component of many, such as advanced transmitters and receivers, which will ultimately be needed to continue building more powerful computers and datacenters.
