Abstract

The light-induced director axis reorientation in a surface-stabilized ferroelectric liquid crystal is investigated experimentally. Several-order-of-magnitude enhancement in light sensitivity and response speed of the director axis reorientation is achieved by incorporation of dichroic dyes into the liquid crystal. A novel scheme for self-aligned spatial filtering by use of the dye-doped liquid crystal is also proposed and is demonstrated with milliwatt laser powers and millisecond updating times.
