Nanostructured Surfaces for Integrated Optoelectronics, Plasmonics, and Quantum Optics
Abstract
All-optical integrated circuits, which consist of photonic transistors and logic circuits completewith on-chip light sources and detectors, have long been a major goal for scientists and engineersbecause they may allow ultra-fast computing with ultra-low power consumption. The actualrealization of this dream has been very difficult, however, because photons rarely interact witheach other and, even with the aid of nonlinear optical materials, interact very weakly. The goal ofthe proposed research is to leverage recent advances in photonics, plasmonics, optoelectronics,and quantum optics and develop new material and technology platforms for solid-state all-opticalinformation processing. Specifically, we will combine recently developed material andtechnology platforms ~ two-dimensional plasmonic crystals and metasurfaces made of singlecrystallinesilver, silicon-vacancy centers in nanostructured diamond, and two-dimensionaltransition metal dichalcogenides ~ and realize integrated all-optical devices and logic circuits thatwork all the way down to the single-photon level. Examples of these devices include singlephotontransistors, chiral photon routers, electrically tunable plasmon switches and modulators,and on-chip light sources and detectors. Importantly, because the foundational structures are twodimensionaland can be defined using top-down methods, there is a clear path forward tocombine these devices on a single chip and construct integrated circuits. The proposed researchwill lay the scientific and technological foundation for solid-state devices for integrated allopticalcomputing, and as such, has the potential to revolutionize many research areas andapplications that are important to the DoD mission, including data communication andcomputing, signal processing, energy conversion, and even sensing, and imaging. The proposedresearch, which stands firmly at the cross section between nanoscience, materials science, andquantum science, should provide an ideal educational ground for the next generation of scientistsand engineers for the defense and national security workforce.
