Laser-induced nonlinear crystalline waveguide on glass Efficient second harmonic generation has been observed from the laser-induced crystalline waveguide, using a 976 nm diode pump. 13 μW of 488 nm output has been observed from a 17 mm long waveguide with 26.0 mW of launched diode pump power, corresponding to a normalized conversion efficiency of 4.4%W −1. 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 … Nonlinear Group IV photonics based on silicon and 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

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. Efficient second-harmonic generation in nonlinear ... containing a nonlinear dielectric waveguide, to realize an efficient nonlinear optical process with two-dimensional (2D) confinement in subwavelength scale. Specifically, we investigate the second-harmonic generation (SHG) in this structure with the aid of quasi-phase-matching (QPM) technique [12].
