We imagine a world where diseases like cancer, Alzheimer's and tuberculosis are detected and cured with light; where solar cells provide abundant clean energy; and where cell phones compute at the speed of light. We then strive to make that future a reality through development of new nanophotonic materials, methods, and devices.

I. Optical Wavefront Shaping Devices:
David and coauthors have developed a platform for efficient and reconfigurable optical wavefront shaping devices based on tuning high quality factor resonances with electro-optic materials. The ability to dynamically modulate and tune the optical response of phase gradient metasurfaces in this way opens the door to highly efficient and solid state AR/VR, LiDAR, and sensing technologiesII. Plasmons Modify Nanoparticle Dynamics:
Katherine and co-authors demonstrate how plasmons modify nanoparticle transformation dynamics, using in situ transmission electron microscopy to watch how electromagnetic enhancement can induce dehydrogenation at otherwise unreactive sites. These results suggest how optical excitation can unlock new material configurations and reactive sites in catalysts.III. Colorimetric Metasurfaces for Tissue Diagnostics:
Lisa and Co-authors introduce a guided-mode-resonant dielectric metasurface which can be leveraged for colorimetric imaging of material anisotropy in fibrous biological tissue. Their approach opens the door to a variety of potential all-optical applications to diagnose tissue affected by diseases such as Alzheimer’s disease, heart disease or cancer.
