摘要：

This paper presents a theoretical model of a wavelength-locking loop for stabilization of the output wavelength in multisection tunable lasers for their application in future dynamic optical burst-switched networks. The linearized theoretical model was used to derive expressions for the optimal PID coefficients of a control circuit for etalon-based wavelength-locking control loop as a function of the key loop parameters. The validity of the model was then experimentally verified by measurements of locking performance of a digital supermode-distributed Bragg reflector tunable laser based on the proposed model.
