Terahertz Days: Plasmonic Terahertz Optoelectronics

Montreal, Quebec, Canada

Although unique potentials of terahertz waves for chemical identification, material characterization, biological sensing, and medical imaging have been recognized for quite a while, the relatively poor performance, higher costs, and bulky nature of current terahertz systems continue to impede their deployment in field settings. In this talk, I will describe some of our recent results on developing fundamentally new terahertz electronic/optoelectronic components and imaging/spectrometry architectures to mitigate performance limitations of existing terahertz systems. In specific, I will introduce new designs of high-performance photoconductive terahertz sources that utilize plasmonic nanoantennas to offer terahertz radiation at record-high power levels of several milliwatts – demonstrating more than three orders of magnitude increase compared to the state of the art. I will describe that the unique capabilities of these plasmonic nanoantennas can be further extended to develop terahertz detectors and heterodyne spectrometers with quantum-level detection sensitivities over a broad terahertz bandwidth at room temperatures, which has not been possible through existing technologies. To achieve this significant performance improvement, plasmonic antennas and device architectures are optimized for operation at telecommunication wavelengths, where very high power, narrow linewidth, wavelength tunable, compact and cost-effective optical sources are 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 screening systems. And finally, I will briefly highlight our research activities on development of new types of high-performance terahertz passive components (e.g., modulators, tunable filters, and beam deflectors) based on novel reconfigurable meta-films.

NASA Systems Engineering: Introduction to Project Life Cycle and Future Developments in Space Exploration.

Montreal, Quebec, Canada, Virtual:

Many engineers seeking to enter the space industry lack insight on project life cycle phases that may impede on project process and aptness to meet both requirements and deadlines. In this talk, I will dissect the different phases that compose Project Life Cycle. This presentation will provide an overview of each phase, including: Concept Studies, Concept and Technology Development, Preliminary Design and Technology Completion, Final Design and Fabrication, System Assembly, Integration and Test, Launch, Operations and Sustainment, and Closeout. The presentation will conclude with an outlook of future technologies for space exploration and settlement. Speaker(s): Nicolas El Tenn, Claudio Alkazzi Montreal, Quebec, Canada, Virtual:
