ABSTRACT
We describe an optically prepared and controlled nematic liquid crystal device, using derivatized methyl red self-assembled monolayers for surface alignment on both of its windows. This material demonstrates both reversible and irreversible photoinduced anisotropy, depending on the availability of oxygen during illumination. One window of the cell was permanently aligned prior to assembly while the other window retained its sensitivity to the orientation of the polarization of a controlling optical beam, leading to either a uniform or twisted state in the nematic cell. The entire management of the cell was thereby achieved without touching the alignment surfaces.

    A normal-mode anisotropic liquid-crystal (LC) gel is demonstrated. In the absence of an electric field, the light polarized along the rubbing direction is scattered. In the voltage-on state, the gel is highly transparent and is independent of polarization. Such a normal mode LC gel exhibits a...
