Highly efficient phase-matched second harmonic generation ... Highly efficient phase-matched second harmonic generation using an asymmetric plasmonic slot waveguide configuration in hybrid polymer-silicon photonics (PDF) High-confined second harmonic generation in nano ... 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 ... Second harmonic generation using IMI grating structure ... In this paper, the nonlinear effect of second harmonic generation (SHG) in insulator-metal-insulator plasmonic waveguides was investigated. Initially, an IMI plasmonic waveguide was simulated and its SHG effect was considered, then an IMI grating structure was proposed to increase the SHG effect and reduce its loss.
Second-harmonic generation is demonstrated using grating-assisted quasi-phase matching, based on waveguide-width modulation or mode-shape modulation. Applicable to any thin-film integrated second-order nonlinear waveguide, the technique is demonstrated in compact lithium niobate ridge waveguides.
1 -7, Y - - Spatial Frequency Multiplier with Active A frequency multiplier with active linearly tapered slot antennas (LTSAs) has been demonstrated at the second harmonic frequency. In each antenna element, a GaAs monolithic microwave integrated circuit (MMIC) distributed amplifier is integrated with two LTSAs. The multiplier has a very wide bandwidth and large dynamic range.

We present an optical microfiber-lithium niobate on insulator (MF-LNOI) hybrid waveguide for efficient second-order nonlinear processes. The structure combines the advantages of low-loss fiber and high-nonlinearity waveguide systems. We demonstrate the possibility of phase matching between fundamental and second harmonics in a wide spectral and dimensional range, and efficient second harmonic
