本文提出了一种波长锁定环的理论模型，用于稳定多段可调谐激光器的输出波长，以供其在未来动态光突发交换网络中的应用。使用线性化理论模型推导基于标准具的波长锁定控制环路的控制电路的最佳 PID 系数作为关键环路参数的函数的表达式。然后通过测量基于该模型的数字超模分布式布拉格反射镜可调谐激光器的锁定性能，通过实验验证了该模型的有效性。
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.
