Abstract
Following Mie theory, nanoparticles made of a high-refractive-index dielectric, such as silicon, exhibit a resonator-like behavior and very rich resonance spectra. Which electric or magnetic particle mode is excited depends on the wavelength, the refractive-index contrast relative to the environment, and the geometry of the nanoparticle itself. In addition, the spatial structure of the impinging light field plays a major role in the excitation of the nanoparticle resonances. Here, it is shown that, by tailoring the excitation field, individual multipole resonances can be selectively addressed while suppressing the excitation of other particle modes. This enables a detailed study of selected individual resonances without interference by the other modes.
