In this talk\, I will d escribe some of our recent results on developing fundamentally new teraher tz electronic/optoelectronic components and imaging/spectrometry architect ures to mitigate performance limitations of existing terahertz systems. In specific\, I will introduce new designs of high-performance photoconducti ve terahertz sources that utilize plasmonic antennas to offer terahertz ra diation at record-high power levels of several milliwatts – demonstratin g more than three orders of magnitude increase compared to the state of th e art. I will describe that the unique capabilities of these plasmonic ant ennas can be further extended to develop terahertz detectors and heterodyn e spectrometers with single-photon detection sensitivities over a broad te rahertz bandwidth at room temperatures\, which has not been possible throu gh existing technologies. To achieve this significant performance improvem ent\, plasmonic antennas and device architectures are optimized for operat ion at telecommunication wavelengths\, where very high power\, narrow line width\, wavelength tunable\, compact and cost-effective optical sources ar e commercially available. Therefore\, our results pave the way to compact and low-cost terahertz sources\, detectors\, and spectrometers that could offer numerous opportunities for e.g.\, medical imaging and diagnostics\, atmospheric sensing\, pharmaceutical quality control\, and security screen ing systems. And finally\, I will briefly highlight our research activitie s on development of new types of high-performance terahertz passive compon ents (e.g.\, modulators\, tunable filters\, and beam deflectors) based on novel reconfigurable meta-films.\n\nCo-sponsored by: Department of Electri cal and Computer Engineering\, University of Illinois at Chicago\n\nSpeake r(s): Mona Jarrahi\, Ph.D\, \n\nBldg: Lecture Center D5\, 804 South Halste d St\, Chicago\, Illinois\, United States\, 60607-7053 LOCATION:Bldg: Lecture Center D5\, 804 South Halsted St\, Chicago\, Illinoi s\, United States\, 60607-7053 ORGANIZER:derric1@uic.edu SEQUENCE:2 SUMMARY:New Frontiers in Terahertz Technology URL;VALUE=URI:https://events.vtools.ieee.org/m/179197 X-ALT-DESC:Description: <br /><p>Although unique potentials of terahertz wa ves for chemical identification\, material characterization\, biological s ensing\, and medical imaging have been recognized for quite a while\, the relatively poor performance\, higher costs\, and bulky nature of current t erahertz systems continue to impede their deployment in field settings.
