MATERIALS FOR NONLINEAR CHIRAL POLYMER PHOTONICS: MULTI-SCALE-MODELING-GUIDED DESIGN AND DEVELOPMENT
Abstract
The objective of this research project is rational design, synthesis and characterization of novel chiral polymer-based nanocomposites with exceptionally large linear and nonlinear optical activities via establishing structure-property relations. We propose a research program that will develop a novel class of flexible materials to profoundly advance the emerging field of chiral photonics. Chiral photonics encompasses the enantioselective control of linear and nonlinear optical (NLO) functions by selective circular polarization (also called photon spin by physicists), and holds great promise for a wide range of key DoD applications, including secure optical communication, beam steering, all optical switching, signature control, quantum computing, bio-detection, and subwavelength imaging. Specifically, we will: (i) Design and synthesize new chiral helical polymers with enhanced magnetic coupling, that results in a large chiral nonlinearity, and (ii) work out the rational design strategies for manufacturing polymer-based nanocomposite materials with the enhanced plasmonic coupling via blending/tethering plasmonic nanoparticles, which can produce major amplification of chiral nonlinearity.
