Paper Abstract

We demonstrate a fast optical modulator capable of switching large amount of optical retardation (a few microns) in less than 1 ms. The result is achieved by employing a dual frequency nematic in cells with high pre-tile alignment and by providing a special addressing scheme that features amplitude and frequency modulated voltage. We explore the effect of time delay and dielectric heating in process of the optical retardation switching.
