Cette publication scientifique pr\u00e9sente une NOUVELLE APPROCHE pour int\u00e9grer des plaques d’onde r\u00e9glables dans des circuits optiques FLDW. Pour ce faire, une couche de cristaux liquides est incorpor\u00e9e dans le guide d’ondes. Le contr\u00f4le de l’orientation du cristal liquide par une tension appliqu\u00e9e induit un retard de phase d\u00e9pendant de la tension, agissant effectivement comme une plaque d’onde d\u00e9pendant de la tension.<\/p>\n
