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.
Claims7
An optical component comprising:
- a gel layer or membrane attached to a surface of a transparent prism, the gel layer or membrane and the surface configured to attenuate or scatter light so as to modulate light of orthogonal polarization substantially similarly;
- 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.
