Abstract

Déphaseur optique (1) comprenant un guide d'ondes (3), et un élément de réglage (4), qui règle la phase d'un rayonnement électromagnétique conduit par un guide d'ondes (3), et qui est relié à une source de tension électrique (6) pour fournir un signal de réglage (7) servant à régler la phase du rayonnement électromagnétique conduit par le guide d'ondes (3). Le signal de réglage (7) est une impulsion de tension électrique (71, 72, 73).
