Abstract
The authors present a general methodology for achieving any amount of pure phase modulation between 0 and 180 degrees by controlling the polarization of light used to address a given ferro-electric liquid crystal (FLC) material. Using this technique, an eight-state phase modulator made by cascading three FLC layers is demonstrated. Motivated by the need for predictable behavior within spatial light modulators (SLMs), experimental data characterizing the point by point spatial uniformity of an FLC device used for 0/90 degree phase modulation also is presented.
