Second harmonic generation. Second harmonic generation (SHG), also called frequency doubling, is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively ‘combined’ to form new photons having twice the frequency of initial photons.
wiched between two high-index layers, a slot waveguide can be formed [43–46], with a large fraction of modal power trapped in the thin layer. Relative to many nonlin-ear materials such as SRO, SRN, chalcogenides, and poly-mers, silicon has a sufficiently large index to form a slot waveguide [47–51]. Moreover, adding a slot layer provides Highly efficient second harmonic generation in hyperbolic Mar 09, 2015 · Sun Y, Zheng Z, Cheng J, Sun G, Qiao G.

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.
The calculated results on second harmonic generation (SHG) show extremely large bandwidth ~ 40 nm. Modal overlap integral up to 0.035 W 3/2 /V can be realized by optimizing the waveguide geometry, much better than previous results on single slot waveguides. Its temperature dependence is … First-Order Forward and Backward Quasi-Phase Matched
Abstract. In this work, we report on the fabrication of 3D laser-written optical-lattice-like structures in a nonlinear KTP crystal to implement 1 × 4 beam splitting. Second harmonic generation (SHG) of green light through these nonlinear waveguide beam splitter structures provides the capability for the compact visible laser emitting devices.
