ABSTRACT:
A deformable reflector includes a plurality of MEMS devices, each having an electrode membrane having a reflective surface thereon, a flat surface, and a pulldown electrode formed in the flat substrate. The electrode membrane has substantially a same flatness of the flat substrate when the electrode membrane comes into contact with the flat substrate across a majority of its surface area in response to a voltage being applied to the pulldown electrode. The electrode membrane has a two-dimensional curvature when no voltage is applied to the pulldown electrode.
