THz Technology: The Move from Scientific to Commercial Applications - 6G, Space & More

  • Jeffrey Hesler, Ph.D.
  • December 7, 2022 at 1 p.m. EST
  • This is a virtual meeting. Please contact Pamela_Morel@uml.edu for the Zoom link.

Abstract:

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 and measurement, ultra-wideband communications, and the use of THz radiometers in space for next generation commercial weather forecasting. This talk will describe two scientific THz examples, the THz local oscillators for the Atacama Large Millimeter-wave Array (ALMA) and an 874 GHz radiometer that was flown on NASA-GSFC's IceCUBE cube satellite. The talk will then present examples where the same base technology is used in THz test and measurement, including broadband signal generation and detection to 5G/6G and THz vector network analysis.

Bio Sketch:
Jeffrey L. Hesler (F'22, M'86, SM'19) is the Chief Technology Officer of Virginia Diodes and an IEEE Fellow. For more than 30 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 the Chair 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.
