Excitation and Imaging of Resonant Optical Modes of Au Triangular Nano-Antennas Using Cathodoluminescence Spectroscopy
Anil Kumar, Kin-Hung Fung, James C. Mabon +2
Cathodoluminescence (CL) imaging spectroscopy is an important technique to understand resonant behavior of optical nanoantennas. We report high-resolution CL spectroscopy of triang…

Thin Film Absorbers Based on Plasmonic Phase Resonances
Yanxia Cui, Kin Hung Fung, Jun Xu +2
We demonstrate an efficient double-layer light absorber by exciting plasmonic phase resonances. We show that the addition of grooves can cause mode splitting of the plasmonic waveg…
