    Figures & Tables(9)
    Localized surface plasmon resonances of silver nanoparticles. (a) Normalized scattering spectra of single silver nanoparticle and silver nanoparticle dimer in shadow point; (b)(c) near-field distributions of single silver nanoparticle and silver nanoparticle dimer at surface plasmon resonance wavelength, respectively
    Examples of enhancement of nonlinear optical effects in plasmonic nanostructures. (a) White-light supercontinuum generation due to electric-field enhancement in gold nanorod dimer antenna[30]; (b) SHG greatly enhanced by double-resonance antenna composed of V-shaped and in-line rods [31]; (c) SHG induced by electric modulation in plasmonic grating[32]
    Enhancement of nonlinear optical effects in hybrid plasmonic systems. (a) SHG enhanced by BaTiO3/Au core-shell structure[39]; (b) SHG induced by hot electrons transfer[63]
    Nonlinear optical effects in strong coupling systems[81]. (a) Schematic of the silver microcavity-nanofiber crystals strong coupling system; (b) anti-crossover dispersion relation of in-plane momentum (k‖) obtained by angle-resolved reflection spectrum; (c) two maxima at 390 nm and 460 nm in SHG signal of the coupled system when wavelength of excitation laser is adjusted from 780 nm to 920 nm
    Nonlinear harmonic generation enhanced by plasmonic nanogap. (a) THG enhanced by plasmonic cavity mode in the gold film coupled gold stripe system[84]; (b) enhancement of THG in hybrid system composed of single ITO nanoparticle and gold rod dimer, which mainly comes from metal region[85]
    Phase matching conditions in nonlinear optics. (a) Most widely used methods for phase matching: birefringence phase matching, angle phase matching, and quasi-phase matching, which allow compensations either in forward or backward directions but cannot compensate at the same time; (b) phase mismatch-free environment created by zero-refractive-index metamaterial for nonlinear propagation, eliminating requirement for phase matching[107]; (c) backward phase-matching process in negative-index materia
    Enhancement of SHG in plasmonic hybrid waveguides. (a) Schematic of SHG excited from silver nanowire-monolayer MoS2 composite structure[116], where inset is Fourier imaging of SHG; (b) schematic of effective SHG excited from hybrid plasmon waveguides[61], where inset is Fourier imaging of SHG
    THG effect in silicon-based plasmonic waveguides. (a) Schematic of effective THG excited from silicon-based micro-nano plasmonic waveguide[115] using incident laser wavelength of 1550 nm; (b) schematic of four-wave mixing excited from silicon-based plasmonic hybrid waveguide[116]
    Nonlinear optical effects in graphene. (a) Hexagonal nanographene sensor, where single charge-carrying/dipole molecule can alter the SHG hyperpolarizability[42]; (b) THG radiation spectrum as a function of the width of graphene nanoribbons in one-dimensional graphene gratings, where inset shows intensity distribution of THG under the excitation of fundamental plasmon mode reaches maximum value in case of double resonance[130]; (c) high-harmonic radiation from graphene nanoribbon[133]
