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: STARaCOM (Mon treal)\n\nSpeaker(s): Mona Jarrahi\, Gunes Karabulut Kurt\n\nAgenda: \n03: 45 PM - 04:00 PM: Connecting to Zoom and welcoming the participants\n\n04: 00 PM - 04:05 PM: Workshop and Speaker introduction by chair of Terahertz Days workshop Series\, Dr. Gunes Karabulut Kurt\n\n04:05 PM - 05:05 PM: Ta lk by Prof. Mona Jarrahi\n\n05:05 PM - 05:30 PM: Q & A session\n\nMontreal \, Quebec\, Canada LOCATION:Montreal\, Quebec\, Canada ORGANIZER:mansour.nch@ieee.org SEQUENCE:11 SUMMARY:Terahertz Days: Plasmonic Terahertz Optoelectronics URL;VALUE=URI:https://events.vtools.ieee.org/m/286633 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.
