"Terahertz Photonics - Passive Components, Active Devices and Systems"

点击翻译按钮获取中文摘要

Our research program over the past five years has targeted the advancement of terahertz technology. This work has been facilitated through several major grants and partnerships with industry leading to considerable expertise and numerous collaborations. With this new Discovery Grant application, we seek to continue research in several promising new directions that have been identified in our prior activities. This work is centered on three main areas: terahertz waveguide technology, terahertz source and detector technology, and terahertz systems. A major objective is to develop components and systems in which terahertz waves are entirely confined within waveguide structures, rather than radiating as free-space beams as is typically done in today's systems. It is anticipated that this work will result in terahertz-based tools and instruments that will offer higher dynamic range, longer sample interaction lengths, lower cost, and more widespread utility than today's free-space terahertz technology.
