Tips vs. holes: ×10 higher scattering in FIB-made plasmonic nanoscale arrays for spectral imaging
Abstract
FIB-fabricated plasmonic nanoholes and nanoprotrusions designed as hyperspectral imaging pixels are compared. Nanoprotrusions scatter nearly ten times more strongly and exhibit red-shifted resonances. A self-referencing hyperspectral procedure extracts extinction spectra using adjacent gold background.
