DESCRIPTION:Prof Kaushik Sengupta\, Princeton University Department of E
 lectrical Engineering\nSilicon-based Terahertz systems is a field that is 
 only about a decade old. In this time\, we have seen a phenomenal growth o
 f silicon systems operating at THz frequencies for a wide range of applica
 tions in sensing\, imaging and communication. It can be argued that both t
 he ‘THz gap’ and the ‘technology and applications gap’ is closing 
 in meaningful ways in the THz range. Technologies beyond 100 GHz focusing 
 on sensing\, imaging and wireless back-haul links are getting attractive a
 s we enter into a new area of highly dense network of autonomous systems r
 equiring ultra-high speed and reliable links.\nIn order to move beyond thi
 s inflection point as Moore’s law continue to slow\, I will discuss why 
 we need to look beyond the classical ‘device’-level metrics of efficie
 ncy and sensitivity of THz sources and detectors towards holistic ‘syste
 m’ level properties such as scalability and programmability. Such proper
 ties are critically important for applications in sensing and imaging\, as
  evidenced across sensor fusion technologies across mmWave\, IR and optica
 l frequencies. The ultimate programmability in THz sources and sensors is 
 one that can synthesize or receive THz fields with arbitrary configuration
  and spectrum. In this talk\, I will highlight approaches that cut across 
 electromagnetics\, circuits\, systems and signal processing\, to allow for
  such reconfigurability in THz signal synthesis and sensing\, yet realized
  with devices that are themselves not very efficient. Particularly\, we wi
 ll demonstrate approaches to THz CMOS sensors reconfigurable across the th
 ree field properties of spectrum (100 GHz-1000 GHz)\, beam pattern and pol
 arization\, programmable THz metasurfaces with CMOS tiling\, and enabling 
 dynamic spectrum shaping and physically secure sub-THz links. In the end\,
  I will comment on what could be the major directions for the field in the
  coming decade.
