This team will leverage established and new chiral nanostructures and expertise in plasmonic and Raman optical activity measurements to explore the fundamental relationship between the local electromagnetic near-field and the far-field chiral response. Because nanoscale chiral structures interact much more strongly with circularly-polarized light than molecules, the measured asymmetric responses can be orders-of-magnitude larger. As such, chiral nanostructures have great potential to impact waveguiding, display, security tag, and sensing technologies.
