ABSTRACT:
A light-modulating device and method are disclosed. The device comprises an optically transparent working electrode in contact with an electrolyte layer, and a counter electrode 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. Also disclosed is a method of manufacturing a light-modulating device.
