Optical characteristics of wavelength-optimized reflective FLC SLMs

摘要

Abstract: we demonstrate 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 $MUL 256 SLM cells were prepared from a single silicon wafer. These cells were filed wit five different FLC materials 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 1000nm. !3
