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 nanoantennas to offer terahert z radiation at record-high power levels of several milliwatts – demonstr ating more than three orders of magnitude increase compared to the state o f the art. I will describe that the unique capabilities of these plasmonic nanoantennas can be further extended to develop terahertz detectors and h eterodyne spectrometers with quantum-level detection sensitivities over a broad terahertz bandwidth at room temperatures\, which has not been possib le through existing technologies. To achieve this significant performance improvement\, plasmonic antennas and device architectures are optimized fo r operation at telecommunication wavelengths\, where very high power\, nar row linewidth\, wavelength tunable\, compact and cost-effective optical so urces are commercially available. Therefore\, our results pave the way to compact and low-cost terahertz sources\, detectors\, and spectrometers tha t could offer numerous opportunities for e.g.\, medical imaging and diagno stics\, atmospheric sensing\, pharmaceutical quality control\, and securit y screening systems. And finally\, I will briefly highlight our research a ctivities on development of new types of high-performance terahertz passiv e components (e.g.\, modulators\, tunable filters\, and beam deflectors) b ased on novel reconfigurable meta-films.\n\nCo-sponsored by: Dr. Mehrdad S harbaf IEEE CLAS Computer Society Chair\, Adjunct Professor CSUDH\n\nSpeak er(s): Professor Mona Jarrahi\n\nVirtual: https://events.vtools.ieee.org/m /416945 LOCATION:Virtual: https://events.vtools.ieee.org/m/416945 ORGANIZER:msharbaf@csudh.edu SEQUENCE:26 SUMMARY:New Frontiers in Terahertz Technology URL;VALUE=URI:https://events.vtools.ieee.org/m/416945 X-ALT-DESC:Description: <br /><p class="MsoNormal" style="text-align: justi fy\; mso-layout-grid-align: none\; text-autospace: none\;"><span style="fo nt-size: 10.0pt\;">Although unique potentials of terahertz waves for chemi cal identification\, material characterization\, biological sensing\, and medical imaging have been recognized for quite a while\, the relatively po or performance\, higher costs\, and bulky nature of current terahertz syst ems continue to impede their deployment in field settings.
