Abstract:
1. An optical network comprising: a multidimensional coder and modulator for handling multiple-in-multiple-out MIMO spatial lightpath properties and content of any specific supercarrier; a spatial mode multiplexer responsive to orthogonal frequency division multiplexing OFDM transmissions and said multidimensional coder; a spatial-spectral routing node coupled over a fiber link to said spatial mode multiplexer for performing switching granularity by a spatial mode reconnection; a multidimensional decoder and demodulator; and a spatial mode demultiplexer coupled over a fiber link to said spatial-spectral routing node and responsive to said multidimensional decoder and demodulator, wherein said spatial-spectral routing node comprises tunable lasers for wavelength grooming into a band, tunable filters for selection of a specific band and a mode-connection conversion scheme from a spatial side; wherein said multidimensional coder and modulator comprises a continuous wave laser diode signal being split into N branches by using a power splitter to feed 2M
