Abstract
A structure for the phase modulation of light (,) incident upon said structure comprises a mirror (,), a deformable and transparent dielectric (,) disposed on the mirror (,), at least two electrodes (,) having one or several fixed potentials and being adapted to have one or more control voltages applied thereto for generating an electric field (,) in at least a partial region of said dielectric (,), thereby changing the optical path length of the light passing through said dielectric (,) with respect to a state of the dielectric (,) in which the electric field is not applied thereto. An arrangement of a plurality of such phase-modulating structures applied on a CMOS active matrix constitutes a very large scale integrated spatial light modulator.
