Efficient frequency conversion techniques are crucial to the development of plasmonic metasurfaces for information processing and signal modulation. In principle, nanoscale electric-field confinement in nonlinear materials enables higher harmonic conversion efficiencies per unit volume than those attainable in bulk materials. Here we demonstrate efficient second-harmonic generation (SHG) in a

We theoretically analyse quasi-phase matched second harmonic generation in a quadratic slot waveguide. Our results show that in this system both fundamental frequency and second harmonic (SH) modes can be confined in a nano-sized low-index region with the mode overlap integral intensity two orders larger than that achieved in the form birefringence phase matching slot waveguide and the ... Efficient second harmonic generation from mid-infrared to ... second harmonic generation (SHG) processes in LiNbO3 and AlGaAs-based HPW, respectively. However, the non-linear HPW they proposed are not compatible with sili-con photonics. In this Letter, we propose a silicon-organic hybrid plasmonic waveguide (SOHPW) easily amenable to fabrication with a nonlinear polymer (NP) in the slot, as shown in Fig. 1.
