Self-accelerating optical beams have attracted much attention for potential applications in obstruction-evading bendable free-space communication systems. In this work, accelerating plane-wave beams are used to enable a spatially multiplexed multi-channel free-space optical communication scheme. A method for generating and sorting an accelerating plane-wave beam family is proposed and experimentally verified. Employing a family of Airy plane-wave beams in particular, a 7-channel optical communication system with 56-Gbit/s OOK signal per channel transmitted along a parabolic trajectory is demonstrated with an increase in the ability to evade obstructions of up to 0.6 beam waist over that of Gaussian beams.
