Abstract: An electro-optic modulator is disclosed with reduced switching voltage. The electro-optic modulator includes a modulator material film layer. The modulator material film layer includes a polymer matrix. Droplets of liquid crystals are dispersed within the polymer matrix. The liquid crystals are configured to modulate light transmissivity through the electro-optic modulator. Alkanes are dispersed within the droplets. The alkane additives reduce the switching voltage of the electro-optic modulator. n-decane and mineral oil compositions are experimentally demonstrated to reduce the switching voltage.

Abstract: An electro-optic modulator is a liquid-crystal-based electro-optical light modulator. The liquid-crystal-based electro-optical light modulator is fabricated using surface Micro-electromechanical Systems (MEMS) techniques. The electro-optical light modulator is used for inspecting flat panel displays or the like. Utilizing surface MEMS techniques for fabrication considerably thins the electro-optic modulator and allows the use of pure liquid crystal without the need for thick containment plates.

Abstract: An electro-optic modulator is disclosed. The electro-optic modulator includes a modulator material film layer. The modulator material film layer includes a polymer matrix. Liquid crystals and getter molecules are dispersed within the polymer matrix. The liquid crystals are configured to modulate light transmissivity through the electro-optic modulator. The getter molecules capture or coordinate with cationic impurities present within the polymer matrix. By gettering the cationic impurities, switching of the device at modulated low frequencies are improved as well as a reduction on the switching voltage of the device. Three classes of getter molecules have been so far demonstrated to work: inorganic ion traps (dihydrogen ammonium phosphate), organic cation traps (EDTA), and organic ion extractors (nicotinic acid). An amount for the getter molecules may be 0.01 to 1.0 percent by weight of the polymer matrix.
