| Research Abstract |
Numerical simulation method of liquid-crystal(LC) molecular orientation is prepared for the purpose of the realization of new type LC optical devices by using an impedance network model. Then some properties of several LC optical devices are analyzed. The LC cells with distributed layer of dielectric constant or impedance between an electrode and LC layer are fabricated by arranging the distribution of sub-wavelength ferroelectric nano-particles. Effective refractive index distribution and optical properties are investigated by applying a voltage across the electrodes, and voltage controllable optical properties such as a prism and lens are demonstrated. In addition, new types of LC optical devices are proposed.
