Abstract
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.
