Decision Algorithm for Orbital Angular Momentum Receiver

A new scheme for an OAM communications system which exploits the radial component p of Laguerre Gauss modes in addition to the azimuthal component l generally used is presented. We derive a new encoding algorithm which makes use of the spatial distribution of intensity to create an alphabet dictionary for communication. We investigate the probability of error in decoding, for several detector options. A possible application could be improved communication modality for data center networks.
