This paper presents on an enhancement of the second harmonic generation of plasmonic metal nanoparticles through the simultaneous application of two strategies, that is, introducing an optical interference layer on the substrate and hybridizing with NLO polymer simultaneously.
The optical interference effect was achieved using thermally oxidized silicon as the substrate.
The higher optical field is provided by taking advantage of the optical interference inside the oxide layer, and it is used for creating surface plasmon polarizations more efficiently.
The NLO polymer is a material that possesses a large second-order nonlinear susceptibility. Growing this material on the surface of plasmonic metal nanoparticles increases their surface nonlinearity.
The SHG conversion efficiency of the proposed system is approximately 50 times as high as that of the standard plasmonic metal nanoparticles.
