DESCRIPTION:Silicon-based Terahertz systems is a field that is only about a
  decade old. In this time\, we have seen a phenomenal growth of silicon sy
 stems operating at THz frequencies for a wide range of applications in sen
 sing\, imaging and communication. It can be argued that both the ‘THz ga
 p’ and the ‘technology and applications gap’ is closing in meaningfu
 l ways in the THz range. Technologies beyond 100 GHz focusing on sensing\,
  imaging and wireless back-haul links are getting attractive as we enter i
 nto a new area of highly dense network of autonomous systems requiring ult
 ra-high speed and reliable links.\n\nIn order to move beyond this inflecti
 on point as Moore’s law continue to slow\, I will discuss why we need to
  look beyond the classical ‘device’-level metrics of efficiency and se
 nsitivity of THz sources and detectors towards holistic ‘system’ level
  properties such as scalability and programmability. Such properties are c
 ritically important for applications in sensing and imaging\, as evidenced
  across sensor fusion technologies across mmWave\, IR and optical frequenc
 ies. In this talk\, I will highlight approaches that cut across electromag
 netics\, circuits\, systems and signal processing to enable THz beamformin
 g arrays\, CMOS sensors reconfigurable across the three field properties o
 f spectrum (100 GHz-1000 GHz)\, beam pattern and polarization (Nature Comm
 ’19)\, programmable THz metasurfaces with CMOS tiling (Nature Elec’20)
 \, and enabling dynamic spectrum shaping (ISSCC’21\, JSSC’21) and phys
 ically secure sub-THz links (ISSCC’20\, Nature Elec’21). In the end\, 
 I will comment on what could be the major directions for the field in the 
 coming decade.\n\nCo-sponsored by: IEEE Future Networks Technical Communit
