Abstract

We report multicasting data from a single orbital angular momentum (OAM) spatial channel onto multiple OAM channels of equally spacedOAMcharge numbers. The designed sliced phase patterns for multicasting are loaded on the spatial light modulator. By optimizing the design of the phase pattern, the power of multicasted OAM channels can be equalized. We experimentally demonstrate multicasting five and seven OAM channels from a single-input OAM channel carrying a 100 Gbit/s quadrature phase-shift keying (QPSK) data stream.
