Abstract:

The past 5 years have seen a dramatic expansion of interest in THz technology outside the traditional scientific community. As one example, there has been worldwide interest in so-called 6G communications, with links proposed by major telecom companies to 320 GHz and higher. This move from a field dominated by scientific applications to a more generally available technology is something that has been key to the path of Virginia Diodes (VDI) over the past 25 years. This talk will give examples of this evolution of THz technology as evidenced by projects at VDI. First, the talk will discuss work on THz radiometers at frequencies ranging from 50 GHz to 2.5 THz for applications ranging from fusion plasma, planetary sciences and weather forecasting. This same basic THz technology has been applied to THz test and measurement, which is a key enabling technology to move the THz field forward and enable these commercial applications. Examples will include the generation and detection of wideband signals, vector network analyzers for device characterization, vector component analyzers for nonlinear device characterization, active load pull to 300 GHz, and noise measurement methods.

Bio: Jeffrey L Hesler (M’86–SM’19–F'22) is the President & 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 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 the IEEE Technical Committee MTT-21 (Terahertz 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.
