A novel interferometric configuration for orbital angular momentum (OAM) mode multiplexing/demultiplexing, based on the image transformation property of pairs of cylindrical lenses and without any splitting loss, is proposed. The effectiveness in mode demultiplexing has been experimentally proven by performing bit error rate measurements for a 20 Gbit/s mode division multiplexing communication system where two modes with different values of OAM, corresponding to the angular indices l = 0 and 1, respectively, are transmitted.

Abstract
A novel interferometric configuration for orbital angular momentum (OAM) mode multiplexing/demultiplexing, based on the image transformation property of pairs of cylindrical lenses and without any splitting loss, is proposed. The effectiveness in mode demultiplexing has been experimentally proven by performing bit error rate measurements for a 20 Gbit/s mode division multiplexing communication system where two modes with different values of OAM, corresponding to the angular indices l = 0 and 1, respectively, are transmitted.File in questo prodotto:
