Deep-Space and Near-Earth Optical Communications by Coded Orbital Angular Momentum (OAM) Modulation

In order to achieve multi-gigabit transmission (projected for 2020) for the use in interplanetary communications, the usage of large number of time slots in Pulse-Position Modulation (PPM), typically used in deep-space applications, is needed, which imposes stringent requirements on system design and implementation. As an alternative satisfying high-bandwidth demands of future interplanetary communications, while keeping the system cost and power consumption reasonably low, in this paper, the authors describe the use of Orbital Angular Momentum (OAM) as an additional degree of freedom.
