Fabrication of terahertz antenna for THz spectroscopy applications

太赫兹(THz)电磁波的频率为10^12赫兹，波长为100微米。在过去的十年里，太赫兹光谱用于材料成像/传感和表征受到了极大的关注。研究表明，包括有机材料、炸药、药物化合物和生物制剂在内的许多材料在太赫兹频率上都有明显的特征。因此，它在制药工业、食品工业、有机发光二极管、安全、航空航天、石油工业、医学成像、医药以及高数据速率通信等领域具有潜在的应用前景。太赫兹辐射的显著特征，以及使能技术的最新进展，为太赫兹技术创造了机会，为许多关键的工业问题提供独特的解决方案。TeTechS Inc.(www.etechs.com)是一家太赫兹技术解决方案公司，致力于开发用于工业和科学应用的太赫兹传感器和成像系统。TeTechS Inc.目前向世界各地的工业和学术客户提供从光导天线芯片到太赫兹光谱系统的各种尖端太赫兹产品。目前的项目旨在制造：(1)垂直结构的光导芯片，与普通的平面交指光导天线相比，其性能有所改善；(2)可以工作在电信波长(1550 Nm)并可与光纤耦合的光导天线，这将缩小紧凑型太赫兹光谱系统的尺寸；以及(3)甚高频太赫兹天线。

Terahertz (THz) electromagnetic waves have frequencies of order 10^12 Hz and wavelengths order 100 um. Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. It has been shown that many materials including organic materials, explosives, pharmaceutical compounds and biological agents have distinct signatures in the terahertz frequencies. It thus has potential applications in areas such as the pharmaceutical industry, food industry, organic light emitting diode, security, aerospace, oil industry, medical imaging, medicine, as well as high-data-rate communications. The distinct characteristics of terahertz radiation, along with recent advances in the enabling technologies, have created the opportunity for the terahertz technology to provide unique solutions to many critical industrial problems.TeTechS Inc. (www.tetechs.com) is a terahertz technology solution company committed to developing terahertz sensor and imaging systems for industrial and scientific applications. TeTechS Inc. is currently offering a variety of leading-edge terahertz products ranging from photo-conductive antenna chips to terahertz spectroscopy systems, to industry and academic customers worldwide. The current project aims to fabricate: (1) photoconductive chips with vertical structure that has improved performance compared to the common planar interdigitated photo-conductive antenna; (2) photo-conductive antennas that can work at telecom wavelength (1550 nm) and can be coupled to fiber optics, which would reduce the size for compact terahertz spectroscopic systems; and (3) very high frequency terahertz antennas.
