Title:
LATERAL FIELD BASED LIQUID CRYSTAL GRATINGS
Document Type and Number:
WIPO Patent Application WO2001037039
Kind Code:
A9
Abstract:
An electro-optic polarizor, grating assembly or cell (10) includes a first glass plate (12) to form the foundation of the cell. A first alignment surfactant (14) is coated on one surface of the first glass plate (12). Similarly, a second alignment surfactant (24) is coated on one surface of a second glass plate (22). A transparent interdigitated electrode pattern (30) is disposed between the second glass plate (22) and the second alignment surfactant (24). A thin film of homeotropically aligned nematic liquid crystal (40) is sandwiched between the first and second alignment surfactants (14) and (24) for applying a lateral electric field caused by the control voltage or signal (50) across the liquid crystal (40) to alter the optical properties of the liquid crystal (40) such that a polarization depended grating (60) is induced by the lateral electric field (50).
