POLYMER DIELECTRIC COATINGS USED TO CONSTRUCT LIQUID LENS

An electrowetting optical device is provided. The electrowetting optical device includes a first window, a second window, and a cavity disposed between the first window and the second window. The electrowetting optical device additionally includes a first liquid and a second liquid disposed within the cavity, the first liquid and the second liquid substantially immiscible with each other and having different refractive indices such that an interface between the first liquid and the second liquid defines a variable lens. The electrowetting optical device also includes a common electrode in electrical connection with the first liquid and a driving electrode disposed on a sidewall of the cavity and insulated from the first liquid and the second liquid by an insulating polymer dielectric layer. The insulating polymer dielectric layer may be formed using initiated chemical vapor deposition (iCVD).
