<title>Optical characteristics of wavelength-optimized reflective FLC SLMs</title>

Abstract

We demonsirate that with a single manufacturing process and custom FLC materials, individual reflective FLC SLMs can be optimized for a wide range of chosen wavelength regions. One lot of 256 x 256 SLM cells were prepared from a single silicon wafer. These cells were filled with five different FLCmaterials having birefringence spanning a range from 0. 129 to 0.218. The resulting retardance variation allowed SLM characteristics to be tailored to give optimized performance in any wavelength region from 400nm to l000nm.
