Title (EN) OPTICAL SWITCHING DEVICES
(FR) DISPOSITIFS DE COMMUTATION OPTIQUES
Abstract: front page image
(EN)The invention provides an optical switcing device, including a substrate (10) having at least one polarization-selective multiplexing grating (H3); at least one polarization-selective demultiplexing grating (H4), and a polarization rotation element (6) acting as a dynamic 1/2 $g(l) plate, optically interposed in the optical path between said multiplexing grating and said demultiplexing grating. The invention also provides a method for producing an holographic plate having a plurality of holographic elements.
(FR)L'invention concerne un dispositif de commutation optique. Ce dispositif comprend un substrat présentant au moins un réseau de multiplexage sélectif par polarisation, au moins un réseau de démultiplexage sélectif par polarisation et un élément de rotation par polarisation agissant comme une plaque dynamique de ½ $g(l), interposé de manière optique entre la trajectoire optique dudit réseau de multiplexage et ledit réseau de démultiplexage. La présente invention concerne aussi un procédé de production d'une plaque holographique présentant plusieurs éléments holographiques.
