Electro-optic Polymers for Wideband Terahertz Applications

太赫兹光电器件、成像和光谱学在商业应用中具有广泛应用的潜力。该项目将重点开发基于电光聚合物复合材料的宽带太赫兹器件。重点将放在两个重要的应用上：(1)开发比目前可用的带宽更宽的太赫兹发射器-探测器对；(2)开发用于直接成像应用的大面积太赫兹探测器。目标不仅仅是展示最高的探测频率，而是开发一种超宽带发射器-探测器对，这将对太赫兹波段的光谱应用产生重大影响。除了这两个主要目标之外，详细的测量和分析将在太赫兹区域内对各种电光和光折变聚合物复合材料进行。这些研究将有助于发展关于这些材料和器件的知识体系，这些知识将有助于理解和弥合超高速电子器件和光子器件之间的差距。

THz optoelectronic devices, imaging, and spectroscopy have the potential for widespread use in commercial applications. This program will focus on the development of wideband THz devices based on electro-optic polymer composites. Focus will be placed on two important applications: (1) the development of a THz emitter-detector pair that has significantly wider bandwidth than is currently available and (2) the development of large area THz detectors for direct imaging applications. The goal is not merely to demonstrate the highest frequency of detection but rather to develop an ultra-wide bandwidth emitter-detector pair that will have significant impact on spectroscopic applications in the THz regime. In addition to these two major goals, detailed measurements and analysis will be performed and on various electro-optic and photorefractive polymer composites in the THz regime. These studies will help to develop a body of knowledge about these materials and devices that will be needed to understand and bridge the gap between very high speed electronic devices and photonic ones.
