Abstract
Procédé pour la régulation de la puissance de sortie d'un laser à semi-conducteurs destiné à un système de transmission d'information par fibre guide de lumière. Une photodiode transparente FD est insérée dans la fibre F1, F2 pour découpler une partie de la puissance utile. Elle délivre une tension de réglage permettant de maintenir constante la puissance de sortie du laser LD.
