9901585PatelThis project will undertake an examination of the structural and the electro-optic properties of cholesteric liquid crystals and explore possible device applications of these materials. The project's primary focus will be a detailed study of the origins of the characteristic oily streaks textures and other defect structures in cholesteric liquid crystals, which we believe have hindered the utilization of these materials in unique-optical and electro-optical devices. It is expected that the understanding that may come from the project would pave the way to make better monodomain samples which would simplify the interpretation of experiments, lead to a better understanding of these materials, and allow optical quality devices to be constructed.%%%Due to the explosive growth in the use of the internet, there is a growing need for wavelength selective components for use in the Wavelength Division Multiplexed architecture that will increase the bandwidth of the optical fiber. We expect that the proposed research project will lead to new device structures for use the next generation of optical networks.

9901585Patel该项目将进行结构和电光性能的液晶的检查，并探讨这些材料的可能的设备应用。 该项目的主要重点将是详细研究液晶中特有的油性条纹纹理和其他缺陷结构的起源，我们认为这些缺陷阻碍了这些材料在独特的光学和电光器件中的应用。 预计该项目可能带来的理解将为制造更好的单畴样品铺平道路，这将简化实验的解释，从而更好地理解这些材料，并允许构建光学质量器件。由于互联网使用的爆炸性增长，对用于波分复用架构的波长选择组件的需求不断增长，这将增加光纤的带宽。 我们希望，拟议的研究项目将导致新的设备结构，用于下一代光网络。
