Author Correction: Reconfigurable beam system for non-line-of-sight free-space optical communication (Light: Science & Applications, (2019), 8, 1, (69), 10.1038/s41377-019-0177-3)

Addendum: We were recently made aware of the fact that Professor Nabeel A. Riza’s laboratory theoretically proposed earlier a Non-Line of Sight (NLOS) indoor optical wireless communications arrangement with threedimensional optical beamforming via a spatial light modulator using diffuse reflections from diffuse optical elements¹. This is exactly the type of arrangement that would benefit greatly from our technique, since the coherent arrayed optical transmitter (CAO-Tx) we proposed makes the reflection focus onto the receiver, rather than diffusely scatter it in all directions. We apologize for the omission of this prior-art.
