Abstract
An optical device includes a substrate, a first electrode, a second electrode, and a first lens. The first electrode and the second electrode are over the substrate and configured to generate a first electric field. The first lens is between the first electrode and the second electrode and has a focal length that varies in response to the first electric field applied to the first lens.
Claims20
An optical device, comprising:
- a substrate;
- a first electrode and a second electrode over the substrate and configured to generate a first electric field, wherein a lower surface of the first electrode faces an upper surface of the second electrode;
- and
- a first lens stacked between the first electrode and the second electrode and having a focal length that varies in response to the first electric field applied to the first lens, wherein the first lens has an upper surface and a lower surface opposite to the upper surface, and the lower surface of the first lens contacts the upper surface of the second electrode.
