Abstract

ABSTRACT The effect of various alignment films based on both oxides and polymers on dynamic characteristics of light-.addressed nematic liquid crystal spatial light modulators (SLM) has been investigated. The mechanism based on an internal p — i — n diode model has been proposed to interpret an increase in a speed of the SLM using polymer alignment films. 1. INTRODUCTION Spatial light modulators (SLM) with a polymer photosensitive layer, henceforward we shall use the term poly-mer SLM (PSLM) , are known to exhibit some unique characteristics: high resolution inherent in molecular media, as well as high contrast and sensitivity2. Among light-addressed liquid crystal (LC) SLMs, the PSLM shows the highest resolution3.However, temporal characteristics of the PSLM are often worse than those of the SLM with other photosensitive layers. Therefore, a search for ways of an increase in the speed of the PSLM is actual. It was reported in the papers4'5 ,properties of alignment films influenced on the dynamic characteristics of LC-cells significantly.
