Abstract

The need for data storage is rising exponentially – 90% of the world’s data has been created in the last two years and almost 5% of the world’s electricity consumption is currently devoted to storing this massive amount of data. LyteLoop is developing a disruptive alternative to data storage technology using optical communications to store data in motion between objects with higher security and lower power consumption. The technology relies on a patented method of dramatically extending optical path length called Angle Multiplexing, as well as spatial division multiplexing with orbital angular momentum modes to increase data rate in order to store data in space, in optical fiber, or in free-space vacuum cavities. A free-space prototype is under development, which stores data using a high bit rate signal continuously circulating through an Angle Multiplexing system.
