We investigate the sensing of a data-carrying Gaussian beacon on a separate wavelength
as a means to provide the information necessary to compensate for the effects of …

Orbital angular momentum modes do not increase the channel capacity in communication links

M Andersson, E Berglind, G Björk - New Journal of Physics, 2015 - iopscience.iop.org
The orbital momentum of optical or radio waves can be used as a degree of freedom to
transmit information. However, mainly for technical reasons, this degree of freedom has not …
