Abstract:
An electrooptic device comprising:(a) a substrate, (b) a membrane having an optically transparent portion and comprising at least one optically active layer with a refractive index &eegr; and a thickness t, (c) means for directing a beam of light on said optically transparent portion of said membrane, said beam of light having a range of wavelengths with a center wavelength &lgr;, where t=&lgr;/2&eegr;, (d) a flexible support for positioning the optically transparent portion of said membrane at a first position spaced from said substrate and defining an air gap d1 between said optically active layer and said substrate, and a second position spaced from said substrate defining an air gap d2 between said optically active layer and said substrate, and (e) means for applying an electrical bias across said air gap to move said optically transparent portion of said membrane from said first position to said second position.
