Abstract

We use photoemission electron microscopy for hyperspectral imaging of electromagnetic field localization in broken-symmetry III-V semiconductor metasurfaces with high selectivity to characterize complex resonant mode profiles, determine coherent interaction lengths, and corroborate FDTD simulations.
