Op. Gough et al., Zero frequency error DWDM channel synthesis using optical injection-lockedcomb line selection, ELECTR LETT, 35(23), 1999, pp. 2050-2052
The authors demonstrate for the first time the use of optical injection loc
king to synthesise exact frequency WDM channels from a broadband optical co
mb source. Unwanted channel outputs are suppressed by > 30dB relative to th
r selected channel.
