Abstract
An optical device and a fabrication method thereof are provided. The optical characteristics of the optical device are adjustable with a simple structure. An optical device has a first electrode layer, a second electrode layer, and a polymer layer provided between the first electrode layer and the second electrode layer, wherein the polymer layer deforms by application of a voltage and forms a light scatterer on a surface of the optical device.
Claims19
An optical device comprising:
- a first electrode layer;
- a second electrode layer;
- and
- a polymer layer provided between the first electrode layer and the second electrode layer, wherein the polymer layer deforms into a light scatterer on a surface of the optical device by application of a voltage.

A microlens array comprising:
- a first electrode layer;
- a second electrode layer;
- a polymer layer provided between the first electrode layer and the second electrode layer;
- and
- an array of light scatterers on a surface of the second electrode layer produced by application of a voltage.
2 more elements
A method of fabricating an optical device, comprising:
- providing a polymer layer on a first electrode layer;
- providing a second electrode layer on the polymer layer;
- and
- applying a voltage between the first electrode layer and the second electrode layer to cause polymer layer deformation such that a portion of the polymer layer protrudes on a surface of the second electrode layer, thereby forming a light scatterer.
