SRA 3: Transformational Nano-Optoelectronic Soldier Capabilities

SRA3 primarily focuses on understanding fundamental optical, electronic and transport/reaction phenomena in nanostructured materials and learning how to apply these phenomena to enable major advances in portable power, communications, signal processing and detection. One project seeks to harness non-Planck thermal radiation spectra from photonic crystal surfaces and near-field surface emission phenomena to provide compact thermophotovoltaic (TPV) and TPV/thermoelectric solid state electric power generators in the 1-100 We range. Another project studies fundamental mechanisms of photon transport in 3D and 2D materials to enable 2D optical integrated circuits for LIDARs, displays, communications and ultra-fast architectures for neuromorphic, optical deep learning computing architectures. A third team capitalizes on unusual optical resonances in condensed matter arising from Weyl points, other exceptional points, and stable topological bound states within the continuum to advance the state-of-the-art in high power IR and THz lasers for applications to amplifiers, spatial modulators, optical sensing and optical image processing. Another project combines first principles and analytical studies with novel device design and materials synthesis to explore use of topological phenomena (both photonic and electronic) in novel communications, signal detection and signal processing. The fifth project works to establish the basic principles to eventuate multi-scale 3D printing of high functionality fiber devices through synergistic integration of thermal fiber device drawing with 3D printing of the material fed to the draw tower. Objectives of this project are to enable: (a) recursive-manufacturing processes able to introduce nanoscale features into macroscale products in a highly controlled manner; (b) by understanding fluid instability growth rate, new paradigms for creating solid state multimaterial “inks” for conversion into or functionalization of fibers; and (c) the capability to create non-equilibrium micro- and nanostructured multi-material solids of unusual shapes (e.g. Janus and beach ball-like spherical particles) within fibers through capillary breakup of multimaterial fiber cores.
