Demultiplexing using crossphase modulation-induced spectral shifts and Kerr polarisation rotation in optical fibre

Two methods of demultiplexing 5 Gbit/s optical data from a continuous 40 Gbit/s data stream are demonstrated, using both crossphase modulation-induced spectral shifts and the optical Kerr effect in an optical fibre. An all-laser diode configuration was used to obtain these results.
