Abstract

Holographic polymer-dispersed liquid crystals are switchable holograms exhibiting electrically controllable diffraction efficiency. Such devices form the building blocks for several applications under active consideration including spatial light modulators. Several demanding requirements are placed on switchable holograms for these applications, such as high diffraction efficiency, wide on/off dynamic range, low optical scatter, low switching voltage and power consumption, high speed, uniformity and repeatability, low cost, and manufacturability. We describe the challenges and progress in meeting many of these goals.
