Abstract
The possibility of using a ferrielectric liquid crystal as an electro-optic medium for a phase spatial light modulator has been investigated. The electro-optic characteristics of a ferrielectric liquid crystal are measured, and a numerical simulation of a 12-sector spiral phase plate based on this crystal is performed. It is found that, at a sub-kilohertz frequency of phase shift switching modulation by 2π, the investigated liquid-crystal ferrielectric is a lower voltage electro-optic medium for space–time light modulators in comparison with ferroelectric liquid crystals.
