Abstract
A device and a method for reducing polarization-dependent effects in dynamical optical components based on surface modulation of a polymer gel or membrane is disclosed. The device and method modifies, removes or leads away unwanted reflections from incident light or information carrier communicating with said optical component.
Claims21
A method of manufacturing a dynamical optical component having reduced polarization-dependent effects, the method comprising:
- attaching a gel layer or membrane adjacent to a surface of a transparent prism;
- forming a set of individually addressable electrodes on a substrate, wherein the electrodes are spaced apart from a surface of said gel or membrane and facing away from said prism;
- and
- minimizing difference in effects on orthogonal states of polarization in incoming light or an information carrier via the inside of said optical component in a path of said incoming light or said information carrier.

An optical component comprising:
- a gel layer or membrane attached adjacent to a surface of a transparent prism;
- and
- a substrate with a set of individually addressable electrodes spaced apart from a surface on said gel or membrane facing away from said prism, wherein said surface of said transparent prism is diffuse.
A method of using an optical component, the method comprising:
- providing incident light to the optical component;
- directing the incident light to at least one of a gel layer and a membrane attached adjacent to a diffuse surface of a transparent prism, and spaced apart from a substrate with a set of individually addressable electrodes spaced apart from the surface;
- and
- minimizing a difference in effects on orthogonal states of polarization in the incident light.
