Abstract: This invention concerns a method of and a device for optical demultiplexing that are based on the four wave mixing between the signals to be demultiplexed and pump signals. The two signals are fed into a polarisation maintaining fibre (14), which divides them into two components with orthogonal polarisation, separated in time; and the four wave mixing is performed separately on the two components, thereby originating two separate signals that are polarisation-rotated and re-combined.
