Abstract
A modulator for and a method of modulating an incident beam of light including means for supporting a plurality of active elements and a plurality of bias elements, each active and bias element including a light reflective planar surface with the light reflective planar surfaces of the plurality of active elements lying in a first parallel plane and the plurality of bias elements lying in a second parallel plane wherein the plurality of active and bias elements are parallel to each other and further wherein the plurality of bias elements are mechanically or electrically deflected with respect to the plurality of active elements. Each of the plurality of bias elements is deflected an odd multiple of the wavelength of an incident light wave divided by four and the plurality of light reflective planar surfaces of the plurality of active elements move between the first parallel plane to the second parallel plane. The deflection of bias elements is optimized to minimize optical attenuation error due to voltage error.
