Abstract

Comprehensive overview of design requirements and issues in the development of phase-only spatial light modulator (SLM) based liquid crystal on silicon (LCOS) technologies is presented. Phase-only SLMs enable many applications such as holographic three-dimensional (3D) displays, head-up displays for automobiles, laser processing, 3D printers, optical communication, and optical computing. Our LCOS panel can achieve high image quality represented by world-class high contrast ratio. In addition, our LCOS has high reflectivity, high-definition pixels, and high durability against high-power light. In phase-only SLM, high reflectivity means high light use efficiency, high-definition pixels achieve wide-diffraction angle, and high durability against light enables use of high-power laser. In this presentation, we will report a development of phase-only SLM based on LCOS technologies and promising candidates of applications using our phase-only SLM.
