Abstract

The eigen-beams of orbital angular momentum (OAM) have helical wavefront and can be used to construct the channels for free space optical communication, i.e. orbital angular momentum multiplexing (OAMM). It is similar to time-division multiplexing (TDM) and wave-division multiplexing (WDM). We generate four helical beams with different OAM numbers by fork-like grating and modulates them mechanically. The modulated helical beams are then superposed coaxially into one single complex beam. In the receiver, the complex beam is separated into four helical beams with little mutual interference. The experimental results demonstrate the feasibility of OAMM by using the eigen-beams of orbital angular momentum.
