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.

Method and device for reduction of polarization-dependent effects in a tunable optical component

A variable optical modulator for optical communication systems using a tunable dynamic grating comprises a gel or membrane layer attached adjacent to a prism communicating light to/from the optical communication system. A substrate has a plurality of individually addressable electrodes and drive means for providing regulated excitation voltage to each of the plurality of electrodes, thereby generating a wave pattern on a surface of the gel or membrane superimposed on an initial state of the gel or membrane layer.
