Abstract (40-Word Limit): A Spatial Light Modulator is used to optically demultiplex modal channels on the basis of degenerate propagation constants using a shared phase mask for all channels. This allows groups of modes to be routed to common output fibres eliminating the need for MIMO equalization to transmit 2x56Gb/s QPSK over 2km of OM2 grade 50μm core MMF.
