An optical regenerator for regenerating a multi-level phase encoded signal. A first non-linear medium (HNLF) generates a comb of frequency harmonics from the signal under the action of a coherent pump, each component bearing the phase encoded data. A filter selects the first and (M&#x2212;1)th order components. The filtered signal is then input to a second non-linear medium (HNLF) where a further pump is applied, to coherently add the first and (M&#x2212;1)th order components and regenerate the signal by reducing phase noise.
