(FR) FILTRES POUR RESEAU COMPOSITE, DYNAMIQUEMENT RECONFIGURABLE, PERMETTANT DE TRAITER UN SIGNAL TEMPOREL
Abstract
(EN)
Programmable waveguide coders (601) are disclosed that include one or more corrugation segments (609) and one or more spacer segments (613) formed on or in a waveguide defined by a core (605) and the spacer segments (613) are independently controllable with voltages applied to each segment's electrodes (617, 618). The spacer segments (613) permit application of a phase modulation to an input while the corrugation segments act as tunable gratings, wherein a center grating wavelength is tunable by applying a voltage to an electrode associated with the corrugation segment (609). In some embodiments, coders include only corrugation segments (609) or only spacer segments (613). Such coders can be strain tuned or thermally tuned. The coders can be programmatically tuned to code or decode a time-wavelength code or other code.
(FR)
L'invention concerne des codeurs (601) de guide d'ondes programmables, comprenant un ou plusieurs segments ondulés (609), et un ou plusieurs segments intermédiaires (613), formés sur ou dans un guide d'ondes défini par une âme (605), ces segments intermédiaires (613) étant commandés indépendamment par des tensions appliquées à chacune des électrodes de segment (617, 618). Les segments intermédiaires (613) permettent d'appliquer une modulation de phase à une entrée tandis que les segments ondulés agissent comme des réseaux, un signal de réseau central étant accordable par application d'une tension à une électrode associée au segment ondulé (609). Selon certains modes de réalisation, les codeurs comprennent uniquement des segments ondulés (609) ou uniquement des segments intermédiaires (613). Ces codeurs peuvent être accordés par contrainte ou thermiquement. Lesdits codeurs peuvent être accordés par programmation de façon à coder ou décoder un code de signal temporel ou un autre code.
