Plasmonic-electronic integrated circuits have been suggested, but input and output continue to rely on bulky free space optics and inefficient couplers such as prisms. The objective of this project was to study direct electronic generation and detection of plasmons. Since plasmonic-electronic interactions are known in the long-wave IR and THz frequency domains, but not in the optical range usual for plasmonic applications, it was necessary to first develop plasmonic materials and devices for the longer wavelengths. Then, interactions between plasmons and electronics were studied with the long range goal of developing electronic-plasmonic transducers. The work was strongly leveraged by collaborative interactions between the PI, his students, and the AFRL at Hanscom AFB. Research accomplishments are well described in publications that acknowledge this award, including 7 refereed journal papers, 29 conference publications, 3 dissertations and thesis, and one book chapter. The specific accomplishments and topics studied include tunable THz detectors based on plasmon resonances in two dimensional electron gases, new materials for infrared plasmonics, cathodoluminescence study of plasmons on metal gratings, and plasmonic properties of Gold Black nanoparticles.
