The Terahertz field has long been used for a wide variety of scientific applications, ranging from radio astronomy, spectroscopy, fusion plasma diagnostics, and more. The potential of non-scientific applications of THz has been understood for many years, but technological limits slowed the advance of these applications. The past decade has seen dramatic advances in transistor technology that is now enabling rapid progress in a variety of applications, ranging from basic test & measurement, ultra-wideband communications, and the use of THz radiometers in space for next generation commercial weather forecasting. This talk will describe the various THz technologies involved, and give examples of recent projects at Virginia Diodes aimed at advancing THz technology for both scientific and commercial applications.
Jeffrey L Hesler is the Chief Technology Officer of Virginia Diodes and has a visiting position at the University of Virginia. For more than 25 years he has been working on creating new technologies that utilize the Terahertz (THz) frequency band for scientific, defense, and industrial applications. He has published over 200 technical papers in journals and international conferences proceedings, is a member of IEEE Technical Committee MTT-21 (THz Technology and Applications) and is a co-Editor of the IEEE Transactions on Terahertz Science and Technology. Terahertz systems based on his innovative designs are now used in hundreds of research laboratories throughout the world.
