We demonstrate a novel wavelength stabilization technique for use within packet-switched wavelength division multiplexed (WDM) networks. The technique stabilizes transmitters against long-term wavelength drift, as short-term and switching-induced wavelength drifts are considered manageable in WDM networks using channel guard-bands. The accuracy, capture range, and performance of the wavelength stabilization scheme is investigated. Long-term wavelength stabilization of a DBR laser is demonstrated which is suitable for networks with channels spacings of 30 GHz or less.
