Abstract:
A spatial light modulator comprising:a first wafer that is formed from an electro-optic material, a partially reflecting dielectric mirror deposited on the top of the first wafer, a transparent conductor formed on top of the partially reflecting dielectric mirror, a totally reflecting dielectric mirror formed on the bottom face of the first wafer, wherein the first wafer is sandwiched between the totally reflecting bottom dielectric mirror and the partially reflecting dielectric mirror so as to form an asymmetric Fabry-Perot cavity, a second wafer, a metal conductor formed on top of the second wafer, the metal conductor being segmented into a plurality of electrodes, and a plurality of electronic voltage sources formed in the second wafer, each electronic voltage source being located next to a corresponding electrode and applying a voltage between the corresponding electrode and the transparent conductor, the first and second wafers being bonded to one another without being aligned with respect to one another in a predetermined manner.
