Nontechnical Optics, the study of light, is centuries old. The control and manipulation of light has played a critical role in civilization from lenses in the ancient world to modern photonics. This project focuses on polarization, a property of light describing how electromagnetic fields oscillate as light travels through space. This project explores interactions between light and matter in pixels with nanoscale features and demonstrate how to control the polarization of light across a nanopatterned piece of glass or semiconductor. New phenomena arise when many nearby pixels act together. Notably, a phenomenon called resonance arises, wherein light is effectively trapped within the layer of pixels. Resonances offer control over the spectrum of light but conventionally comes at the expense of pixel-by-pixel control of polarization. This project overcomes previous limitations to develop resonant devices made with standard manufacturing techniques and offering pixelated control of the polarization of light. Investigators employ design principles based on symmetries, which simplifies the system and allows new avenues of control of light. Devices made from nanostructured materials are compact and lightweight and can be scaled to mass manufacturing. Understanding developed in this project thus has the potential for technological breakthroughs in holography, imaging, and sensing. In parallel, the PI explores the broadening of knowledge and participation of flat polarization opti
