Title
(EN) DEVICE AND METHOD FOR LIGHT MODULATION
(FR) DISPOSITIF ET PROCEDE DE MODULATION DE LA LUMIERE
Abstract
(EN)
A light-modulating device and method are disclosed. The device comprises an optically transparent working electrode (14) in contact with an electrolyte layer, and a counter electrode (16) contacting the electrolyte layer. The counter electrode is disposed laterally to the working electrode and the path of transmitted light. The method comprises reversible electrocrystallization of a metal from the electrode layer that increases optical density and decreases light transmission.
(FR)
La présente invention se rapporte à un dispositif et à un procédé de modulation de la lumière. Le dispositif comprend une électrode active transparente optiquement (14) en contact avec une couche d'électrolyte, ainsi qu'une contre-électrode (16) en contact avec la couche d'électrolyte. La contre-électrode est placée latéralement à l'électrode active et au trajet de la lumière transmise. Le procédé consiste en une électrocristallisation réversible d'un métal de la couche d'électrolyte qui augmente la densité optique et diminue la transmission de la lumière.
