Abstract: A switchable optical assembly comprises a switchable waveplate configured to be electrically activated and deactivated to selectively alter the polarization state of light incident on the switchable waveplate. The switchable waveplate comprises first and second surfaces and a liquid crystal layer disposed between the first and second surfaces. The liquid crystal layer comprises a plurality of liquid crystal molecules. The first surface and/or the second surface may be planar. The first surface and/or the second surface may be curved. The plurality of liquid crystal molecules may vary in tilt with respect to the first and second surfaces with outward radial distance from an axis through the first and second surfaces and the liquid crystal layer in a plurality of radial directions. The switchable waveplate can include a plurality of electrodes to apply an electrical signal across the liquid crystal layer.
