Abstract

In this paper, we propose and demonstrate a novel and effective wavelength-matching scheme for wavelength grating routers to match their transmission peaks to the wavelength assignment of the data channels without any reference sources. The unused portion of the amplified spontaneous emission (ASE) power of the Erbium doped fiber amplifiers is utilized as the monitoring light source and fiber Bragg gratings of a particular center reflection wavelength is used as the wavelength reference. The scheme supports in- service monitoring and will not degrade the performance of the data channels. It is also insensitive to dynamic ASE power variations arising form channel ad-drop. We have experimentally demonstrated the proposed wavelength-matching scheme for WGR and analyzed the scheme numerically for design optimization.
