This Small Business Innovation Research (SBIR) Phase I project proposes to explore the development of a fundamentally new class of ferroelectric liquid crystals (FLCs) containing germanium. Only one germanium liquid crystal compound has been prepared until this year. A new germanium compound has shown tremendous promise in revolutionizing the scope of FLC devices. The Phase I objectives are to synthesize 20 new compounds and to explore the unique properties of this fundamentally new class of LCs, applying the findings towards commercial application. Anticipated results include an improved understanding of the physical, chemical, and optical properties of these new materials, and the identification of further FLC material and cell advances that need to be achieved in Phase II for subsequent commercialization. The new class of FLCs may afford a more durable device showing broader temperature range and lower birefringence (ease of manufacture), and most of all, operate in both analog and bistable modes.The commercial application of this project is in optical communications. Because germanium FLCs have the potential to afford both analog and bistable operation (a result of bookshelf layer structure) many areas will be opened to commercialization. Phase modulation is the foundation for electro-optical beam steering and optical wave front correction, which find application in free-space optical communications, in beam steering and beam shaping for laser radar in aviation, and in active optics. The new FLCs will also enable higher performance megabit write-heads for emerging holographic data storage, and will be useful for optical information processing. In addition, fast, bistable LCs have been needed for FLC displays, allowing access to the multibillion-dollar projection display market.

这个小企业创新研究（SBIR）第一阶段项目提出探索一种全新的含锗铁电液晶（FLC）的开发。到今年为止，只有一种锗液晶化合物被制备出来。一种新的锗化合物在FLC器件的范围革命方面显示出巨大的前景。第一阶段的目标是合成20种新化合物，并探索这类全新的LC的独特性质，将研究结果应用于商业应用。预期结果包括对这些新材料的物理、化学和光学性质的更好理解，以及确定需要在第二阶段实现的FLC材料和电池的进一步进展，以便随后商业化。这类新型的FLC可以提供一种更耐用的器件，具有更宽的温度范围和更低的双折射（易于制造），最重要的是，可以在模拟和模拟模式下工作。由于锗FLC具有提供模拟和模拟操作的潜力（书架层结构的结果），因此许多领域将开放商业化。相位调制是电光光束控制和波前校正的基础，其在自由空间光通信、航空激光雷达的光束控制和光束整形以及有源光学中得到应用。新的FLC还将为新兴的全息数据存储提供更高性能的兆位写头，并将用于光学信息处理。此外，FLC显示器需要快速的LCD，从而可以进入数十亿美元的投影显示器市场。
