SBIR Phase I: Liquid Crystal Material for High Performance Switchable Multi-Functional Holographic Device

这个小企业创新研究（SBIR）第一阶段项目是通过材料研究来展示创新的可切换全息设备的概念验证。新型全息器件由新型液晶和聚合物复合材料制成，由无液晶液滴的聚合物和液晶平面交替组成，有望在反射效率、开关电压、频谱调谐灵活性、极化灵活性、开关速度和开关模式等方面表现出比现有技术更高的性能。第一阶段的工作将集中在一种特殊的液晶复合材料的开发，从而导致演示设备的构建。除了可切换的布拉格反射外，该演示装置还将展示可调谐的布拉格波长和多种切换模式。新的全息技术可用于制造偏光器、光谱色散元件、光谱可调镜、光开关、光谱滤波器、分束器和组合器，用于光通信、显示和光子学仪器，如分光光度计、激光器、光学成像和检测系统。

This Small Business Innovation Research (SBIR) Phase I project is to demonstrate the proof-of-concept of innovative switchable holographic devices through material research. The new holographic device, made from a novel liquid crystal and polymer composite material, consists of alternating polymer and liquid crystal planes without liquid crystal droplets and is expected to exhibit a higher performance than the prior technologies in terms of reflection efficiency, switching voltage, spectrum tuning flexibility, polarization flexibility, switching speed, and switching mode. The Phase I effort will be focused on a special liquid crystal composite material development that leads to the construction of demo devices. In addition to the switchable Bragg reflection, the demonstration devices will exhibit tunable Bragg wavelength and multiple switching modes. The new holographic technology can be used to build polarizer, spectrum dispersion element, spectrum tunable mirror, optical switch, spectrum filter, beam splitter and combiner for optical telecommunication, display and photonics instrument such as spectrophotometer, lasers, optical imaging and detection systems.
