Abstract
A simple technique for monitoring the optical frequencies of WDM signals us
ing pilot tones and an arrayed-waveguide grating is presented, Results conf
irm that optical frequencies of WDM signals were monitored with an accuracy
better than +/-2 GHz. In addition, unlike the other pilot tone based monit
oring techniques. the proposed technique was not sensitive to the cross-gai
n modulation of EDFAs.
