Improved Sensing with Exceptional Surfaces

Facebook Twitter LinkedIn Email Comments
The ability to optically detect nanoparticles and single molecules could be improved by introducing a sensor that is based on surfaces consisting of highly sensitive exceptional points (EPs), according to research performed by Michigan Technological University, Pennsylvania State University, and the University of Central Florida. The researchers propose a new design concept for implementing photonic EPs that increases the robustness required for practical use of EPs while maintaining their hallmark sensitivity. An exceptional surface-based sensor. The microring resonator is coupled to a...Read full article
