Patent ID: 7898740

Claim:
A tunable optical array device arranged on at least one supporting substrate to form a compound unit comprising: a cell structure of regularly arranged liquid cells having a cell surface, wherein a single liquid cell comprises several cell walls projecting away from the supporting substrate, being closed by a cell base area, and filled with at least two non-miscible liquids or fluids to provide at least one tunable interface area; a control electrode system comprising a plurality of individual addressable cell wall electrodes and at least a counter electrode assigned to each tunable liquid cell for two-dimensionally contact angle tuning and/or interface area position tuning in relation to the cell walls and wherein the cell wall electrodes are conducting layers separately located and coated on a cell wall surface side and isolated to a liquid by an additional isolating coating; an electronic tuning circuitry means assigned to the control electrode system; and a cell addressing means connected with the electronic tuning circuitry means of the control electrode system for separately moving the interface areas.
