The symposium will address critical needs in the fields of nanophotonics, plasmonics, and metamaterials to go beyond standard materials and standard wavelength ranges. The focus of this symposium is on new materials, fabrication techniques, and sample architectures for the developing of both long- and short-wavelength plasmonic and metamaterial devices. Plasmonics and metamaterials are emerging fields that show great promise for confining and guiding light at subwavelength scales. These material structures can be leveraged for a variety of uses including waveguiding, imaging, optical interconnects, light harvesting, biosensing, and many more. To date, significant progress has been made using traditional metals and dielectrics in the visible spectral range. Expanding the operation range of plasmonic devices to longer and shorter wavelengths will enable improvements in the optical infrastructure and advance new technologies. In order to take advantage of plasmonics in these wavelength ranges, new materials and novel device architectures are required that combine novel optical properties with intrinsic or extrinsic mechanisms to mitigate optical losses. The emphasis will be on emerging plasmonic materials including doped semiconductors, two-dimensional/van der Waals materials, nitrides, oxides, transition metals, and noble metal alloys, as well as new device structures and fabrication techniques utilizing traditional metals across the spectrum.
