Optical nonlinearities are intrinsically weak, but can be strengthened in scenarios that provide field enhancement mechanisms. Hybrid structures combining the high inherent material nonlinearity of semiconductors along with plasmonic-induced strong fields are promising platforms for on-chip nonlinear optics. However, due to their complexity, understanding the mechanisms involved is sometimes challenging. Here, the spectral response of metal dimers loaded with an ITO nanoparticle at their gap is investigated numerically and experimentally to provide an understanding and design rules.
