“…In both cases, the frequency conversion efficiency depends on the device length, and therefore relatively large systems are needed, contrary to the current miniaturization requirements in nanophotonics. An alternative route towards improving the efficiency of frequency conversion phenomena in nanoscale dimensions can be provided by combining nonlinear dielectrics with different materials in hybrid architectures [8][9][10][11][12][13]. In particular, new light sources can be designed by associating nonlinear dielectrics with metallic nanostructures supporting localized surface plasmon resonances (LSPs) able to strongly confine and enhance the electric fields involved in the nonlinear process.…”

Abstract:We demonstrate a 60-fold enhancement of the second harmonic generation (SHG) response at the nanoscale in a hybrid metal-dielectric system. By using complex silver nanostructures photochemically deposited on the polar surface of a ferroelectric crystal, we tune the plasmonic resonances from the visible to the near-infrared (NIR) spectral region, matching either the SH or the fundamental frequency. In both cases the SHG signal at the metal-dielectric interface is enhanced, although with substantially different enhancement values: around 5 times when the plasmonic resonance is at the SH frequency or up to 60 times when it matches the fundamental NIR radiation. The results are consistent with the more spatially-extended near-field response of complex metallic nanostructures and can be well explained by taking into account the quadratic character of the SHG process. The work points out the potential of aggregates of silver nanostructures for enhancing optical nonlinearities at the nanoscale and provides an alternative approach for the development of nanometric nonlinear photonic devices in a scalable way.

“…76 The other approach is based on the use of domain-specific reactions and it is designated as ferroelectric lithography. 33,77,78 The fields are used to induce localized chemical reactions, nanopatterned surface functionalization, and photoinduced formation of metallic nanostructures. In one relevant example, patterns of silver nanoparticles are deposited on the PPLN surface from an AgNO 3 solution under UV-light exposure with photon energy higher than the band gap ($3.9 eV) (see Figure 18).…”

The application of evanescent photovoltaic (PV) fields, generated by visible illumination of Fe:LiNbO 3 substrates, for parallel massive trapping and manipulation of micro-and nano-objects is critically reviewed. The technique has been often referred to as photovoltaic or photorefractive tweezers. The main advantage of the new method is that the involved electrophoretic and/or dielectrophoretic forces do not require any electrodes and large scale manipulation of nano-objects can be easily achieved using the patterning capabilities of light. The paper describes the experimental techniques for particle trapping and the main reported experimental results obtained with a variety of micro-and nano-particles (dielectric and conductive) and different illumination configurations (single beam, holographic geometry, and spatial light modulator projection). The report also pays attention to the physical basis of the method, namely, the coupling of the evanescent photorefractive fields to the dielectric response of the nano-particles. The role of a number of physical parameters such as the contrast and spatial periodicities of the illumination pattern or the particle deposition method is discussed. Moreover, the main properties of the obtained particle patterns in relation to potential applications are summarized, and first demonstrations reviewed. Finally, the PV method is discussed in comparison to other patterning strategies, such as those based on the pyroelectric response and the electric fields associated to domain poling of ferroelectric materials.

“…Essentially a simultaneous two-fold self-assembling process, involving either EHD instability acting on the hosting liquid polymer in conjunction with dielectrophoretic (DEP) forces operating on NCs, allows the realization of an active array of microstructures just in a single step. Pyro-EHD and pyro-DEP have been discovered and applied separately as advanced processes for the self-assembling of nanofillers [27]- [29], liquids and polymers, including Polydimethylsiloxane (PDMS) [30]- [34] in a multiscale range (i.e., between 25 to 200 μm diameter) with high degree of uniformity. By controlling the polymer instability driven by EHD, different micro-optical structures can be obtained spontaneously, i.e., spherical or toroidal [35].…”

In this paper, we introduce a single-step selfassembling process aimed at forming two-dimensional (2-D) array microstructures made from a nanocomposite polymer layer in which are dispersed CdSe-CdS nanocrystals. The novelty of the process reported here is that it operates simultaneously as a twofold process where the liquid polymer matrix is self-shaped by electrohydrodynamic pressure as a 2-D array of microstructures, while at the same time, the nanocrystals are self-assembled by dielectrophoretic forces. The proposed approach could inspire future smart fabrication techniques for producing self-assembled lensed nanocomposite layers. In principle, the method is scalable down to diameter lens up to few micrometers.
