Abstract

We demonstrate the communication of three coaxial laser channels using single transmit and receive apertures based on a set of distinct orbital-angular-momentum (OAM)-carrying modes. Each channel is individually modulated using OOK at 40 Mb/s and made incident onto an arrangement of spatial-light modulators (SLMs) that impose OAM. The three generated modes are combined before the transmit aperture. The received beam with superimposed OAM modes is filtered using SLMs to separate the channels, which are subsequently photo-detected. The effects of OAM crosstalk among channels and the selection of OAM modes are analyzed.
