The str Efficient surface second-harmonic generation in slot micro It results from the modulation of the waveguide dispersion by slot structure. The slot structure enlarges the waveguide dispersion by more evanescent field propagating outside the fiber, making β 1 of the pump wave in fundamental mode and β 2 of the second-harmonic wave in high-order mode matched at a shorter wavelength.

Long-range surface plasmon polaritons (Lrspps) are optical surface waves that propagate along a thin symmetric metal slab or stripe over an appreciable length (centimeters). Vigorous interest in Lrspps has stimulated a large number of …
First-Order Forward and Backward Quasi-Phase Matched We propose and design a high-efficiency forward and backward second harmonic generation (SHG) in nonlinear polymer filled silicon slot waveguide known as silicon-organic hybrid (SOH) waveguides. The spatial distribution of second-order nonlinearity, χ(2), of waveguide is altered by periodically poling of nonlinear polymer to achieve quasi-phase matching (QPM) between fundamental frequency and Terahertz emission from a two-color plasma filament in a Terahertz emission in forward direction from a long two-color filament placed in the center of a slot waveguide is reported. The waveguide improves the collection and imaging of the generated THz radiation. By tuning the plate separation and position of the waveguide along the filament axis, the emitted mode can be matched to the collection optics.
