OPTICAL SYNCHRONISATION ARRANGEMENT |
| 摘要 |
An optical synchronisation circuit includes a non-linear optical modulator (NOM). The signal to be synchronised and a reference signal interact within the NOM. Cross-phase modulation produces a spectral shift. The output from the NOM is filtered to produce an error signal.
