摘要：
We describe an electro-optic modulator using ferroelectric liquid crystal. A smectic C* material with a 45-degrees tilt angle is sandwiched between two glass plates with buffing directions perpendicular to each other. This produces a twisted smectic structure in absence of an electric field. When used with polarizers, the twisted structure can be electrically distorted to produce optical modulation on a sub-millisecond time scale using less than 1 V/mu-m.
