Abstract

Ce dispositif ajoute une 'dispersion opposée' à la lumière, pour compenser la dispersion chromatique de la lumière provoquée par la circulation de celle-ci le long d'une fibre optique (246). Ce dispositif comprend un groupement en phase et à formation d'images virtuelles (VIPA) (240), ainsi qu'un dispositif de renvoi de la lumière, lequel est généralement un miroir (254) et peut comporter une lentille (251). Ledit groupement disperse de manière angulaire la lumière et le dispositif de renvoi de la lumière renvoie celle-ci au groupement, afin que la lumière subisse une réflexion multiple à l'intérieur dudit groupement.
