Spatial-Light-Modulator-Based Multichannel Data Transmission by Vortex Beams of Various Orders
We report an atmospheric multichannel data transmission system with channel separation by vortex beams of various orders, including half-integer values. For the demultiplexing of the communication channels, a multichannel diffractive optical element (DOE) is proposed, being matched with the used vor...
