“…A special type of dual plasmonic nanostructures are those with harmonically coupled plasmonic resonances when one resonance is energetically located at an excitation energy and the other resonance is located at a harmonic of the excitation frequency. When compared with individual Au and CuS nanoparticles, enhanced second-harmonic light yield by a factor of 3.3 was observed for Au/CuS nanoparticle films . These resonantly coupled plasmonic nanocrystals are promising candidates for the tunable wide-range emission of upconverted light.…”

Dual plasmonic metal–semiconductor heteronanostructures have been actively investigated due to their outstanding functional characteristics arising from the merging of two materials. In this review, the synthetic approaches, various designs, enhanced properties, and prospective applications of noble metal–nonstoichiometric copper chalcogenide nanosystems are summarized. The tunable size, shape, structure type (solid or hollow), composition, and doping level of the constituents produce several configurations of heteronanocomposites reported here. The colloidal synthetic approaches for the fabrication of dual plasmonic nanomaterials with controllable plasmonic properties are presented as well. The unique features of dual plasmonic nanostructures show synergistic and plasmon resonance coupling effects and enhanced light–matter interactions, which cannot be simply assigned to the mixture of pristine materials. Dual plasmonic hybrid nanosystems are promising candidates for enhanced photocatalysis, photothermal cancer therapy, improved sensing, photovoltaic devices, and upconversion luminescence. In conclusion, a brief outlook of the identified challenges in the area of dual plasmonic noble metal–vacancy-doped copper chalcogenide nanomaterials to be addressed in the nearest future is provided.

“…For example, bow-tie-shaped gold elements [4,5], plasmonic nanogap cavity [6], nanohole array [7], individual nanohole [8], nanoparticles [9], doubly resonant Si nanoresonators [10], MoS 2 on a silicon waveguide [11], film-coupled silver nanostrips [12], graphene-based plasmonic gratings [13,14] and metal gratings [15][16][17][18][19] have been shown to largely enhance the nonlinear optical conversion efficiency. Moreover, heterostructures such as coupled semiconductormetal nanoparticle films [20], polymer/Ag/glass structure [21], and bilayer gold nanopillar-nanoaperture structure [22] have been demonstrated to enhance SHG. The nature of these enhancements is that the electromagnetic fields around and inside the metallic nanostructures are dramatically amplified due to the excitation of surface plasmons (SPs).…”

We report on wavelength-tunable and plasmon-enhanced four-wave mixing (4WM) on an Al grating. When surface plasmons (SPs) are excited at the first and second pump wavelengths, the electromagnetic fields near the grating surface are dramatically enhanced and the corresponding 4WM signals are enhanced by factors of 177 and 42 compared with off resonant conditions. The maximum output power of the 4WM signal is as high as 25 nW. Moreover, by fixing the first pump beam to the SP excitation angle and tuning the second pump beam from 1200 to 1550 nm, we obtain a tunable and enhanced 4WM output from 539 to 600 nm. This setup can potentially be applied to frequency conversion, beam steering and dispersion control.

“…Recently, significantly enhanced nonlinear optical effects due to plasmon–plasmon coupling − were observed in plasmonic heterostructures comprising noble-metal and semiconductor NPs. These heterostructures typically have distinct surface plasmon bands from the metal and semiconductor, respectively: the noble-metal LSPRs are designed to match a harmonic of the semiconductor plasmon.…”

Dual heterostructures integrating noble-metal and copper chalcogenide nanoparticles have attracted a great deal of attention in nonlinear optics, because coupling of their localized surface plasmon resonances (LSPRs) substantially enhances light− matter interactions through local-field effects. Previously, enhanced cascaded third-harmonic generation was demonstrated in Au/CuS heterostructures mediated by harmonically coupled surface plasmon resonances. This suggests a promising approach for extending nonlinear enhancement to higher harmonics by adding an additional nanoparticulate material with higher-frequency harmonic resonances to the hybrid films. Here we report the first observation of enhanced cascaded fourth-and fifth-harmonic generation in Al/Au/CuS driven by coupled LSPRs at the fundamental (1050 nm), second harmonic (525 nm), and third harmonic (350 nm) of the pump frequency. An analytical model based on incoherent dipole−dipole interactions among plasmonic nanoparticles accounts for the observed enhancements. The results suggest a novel design for efficiently generating higher harmonics in resonant plasmonic structures by means of multiple sum-frequency cascades.
