First Claim
Patent Images
1. A device for modulating light, comprising:
- a first layer;
a second layer, wherein a gap is present between the first and second layers and the first layer and second layer are stationary relative to each other;
a third layer disposed in the gap between the first and second layers; and
a control circuit configured to selectively induce an electric field between the first and second layers,wherein the third layer is electrically isolated.
