Abstract :
A method of spatial mode multicasting in OAM modes spatial-division multiplexing is proposed and experimentally demonstrated. By designing the phase pattern of a phase-only spatial light modulator, the input single spatial mode of 100Gbits/s QPSK signal can be multicasted up to 8 spatial OAM modes with crosstalk lower than -20dB.
