Une compensation adaptative de dispersion de mode de polarisation (PMD) est nécessaire pour accélérer et faire progresser les communications optiques actuelles. La combinaison d'un compensateur PMD réglable et de son procédé de contrôle adaptatif permet d'obtenir une compensation PMD adaptative. Dans cet article, nous rapportons un algorithme de contrôle de recherche efficace pour le contrôle par rétroaction du compensateur PMD. L'algorithme est basé sur la méthode de l'escalade. Cependant, la taille du pas change de manière aléatoire pour éviter que la convergence ne soit piégée à un maximum local ou à un plat, contrairement à la méthode conventionnelle d'escalade. Le caractère aléatoire dépend des fonctions de densité de probabilité gaussiennes. Nous avons effectué des simulations de transmission à 160 Gb/s et les résultats montrent que la méthode proposée fournit un contrôle du compensateur plus optimal que la méthode conventionnelle d'escalade.

Abstract: Adaptive polarization mode dispersion (PMD) compensation is required for the speed-up and advancement of the present optical communications. The combination of a tunable PMD compensator and its adaptive control method achieves adaptive PMD compensation. In this paper, we report an effective search control algorithm for the feedback control of the PMD compensator. The algorithm is based on the hill-climbing method. However, the step size changes randomly to prevent the convergence from being trapped at a local maximum or a flat, unlike the conventional hill-climbing method. The randomness depends on the Gaussian probability density functions. We conducted transmission simulations at 160 Gb/s and the results show that the proposed method provides more optimal compensator control than the conventional hill-climbing method.
