Nanophotonics by Design: Reaching the Limits of Light-Matter Interactions
June 17th, 2019 OWEN MILLER Yale University

Nanoscience is developing at a rapid pace, with ever more materials, form factors, and structural degrees of freedom now available. To confront these large design spaces, and leverage them for transformative technologies, new theoretical tools are needed. One emerging approach is “inverse design,” a bottom-up large-scale computational optimization technique for discovering non-intuitive, superior structures. An important alternative is to work top down, surveying the landscape and identifying fundamental limits. Starting with the problem of designing optimal smoke grenades, I will show how the two complementary approaches can enable rapid identification of superior designs operating at their theoretical limits. Convexity and causality serve as foundational constraints, ultimately answering general questions about high-efficiency plasmonics, near-field “blackbodies,” the optimality of 2D vs. bulk materials, and more.
