Abstract :
The authors propose and demonstrate a new wavelength-matching scheme for wavelength grating routers in all-optical transport networks. The wavelength assignment of the data channels and the transmission peaks of the wavelength grating routers can be matched automatically and continuously. The scheme uses the unutilised ASE spectra of the EDFA as the source and a temperature-compensated fibre Bragg grating as the matching indicator. It is also insensitive to dynamic ASE power variations arising from channel add-drop
