“…Apertures efficiently remove heat because of the surrounding metal film having a high thermal conductivity. For the same local intensity, the heating can be four orders of magnitude smaller than similar plasmonic nanoparticles [154]. (These particles are similar in the sense that they create the same local field intensities on resonance.)…”

“…Our measurements and calculations showed that the THG efficiency of the SHR nanostructure strongly depends on its geometry (the nanostructure diameter, the nanorod length, the film thickness), the material of the film, and the refractive index of the medium surrounding the SHR [5]. This behavior is explained by the wellknown strong dependence of the excitation efficiency of localized plasmon oscillations on the geometry of the nanostructure and its local environment, which determines the distribution and amplitude of the electromagnetic field near the nanostructure.…”

“…The absolute value of the transformation efficiency of the excitation radiation into the third harmonic per unit area (the intensity ratio of the third-harmonic radiation and the radiation at the fundamental frequency) is about 10 -5 , which is a record high value for experiments on the THG from single nanostructures [5]. Up to now the maximum conversion efficiency of THG was as high as 3 × 10 -7 and was realized on nanostructures in a shape of a split-ring resonator [6].…”

We propose and experimentally realize sub-wavelength light localization based on optical nonlinearity of a single nonlinear -element in nanoplasmonics -a split hole resonator (SHR). Here, we demonstrate the use of the SHR as a highly efficient nonlinear optical element for: (1) the generation of the third harmonic from a single SHR; (2) the excitation of intense multiphoton luminescence from a single SHR; (3) the realization of a polarization-ultrasensitive nanoelement; and finally, as a practical application, (4) the building up of an all-optical display. I. SHR NANOSTRUCTURE AND ITS MERITSIn this paper, we propose and experimentally realize a novel element for nanoplasmonics that combines a nanoparticle and a nanohole into a new nanoobject. As a particular example of such a new element, we build up a split-hole resonator (SHR) that is composed of a nanorod and a nanohole, as is shown in Fig. 1. One of the main merits of the marriage of the two basic elements of nanoplasmonics, the nanoparticle and the nanohole, is to realize true monopole nanoantenna for light having wavelength of the surface plasmon resonance over a large wavelength range, namely, from the UV to the IR range. At resonance, the peak field intensity in SHR occurs at the single tip of the nanorod inside the nanohole. The peak field in the SHR is much stronger than the peak fields of the nanorod and nanohole, since the field in the SHR is enhanced by the following two mechanisms: the surface plasmon resonance excitation and the lightning-rod effect. Fig. 1. The main idea of the formation of a SHR and its operation, spatial distributions of the near field calculated by the FDTD method for aluminum nanostructures exposed to irradiation at a wavelength of 1560 nm: (a) a nanorod 50 × 180 nm, (b) a nanohole with a diameter of 400 nm in an aluminum film 50 nm thick, (c) an SHR nanostructure formed by the nanohole (b) and the nanorod (c).The use of SHRs in nonlinear nanoplasmonics is of special interest for the following reasons [1,2]: (i) the nanohole ensures the absence of a background from the excitation radiation, which is strongly weakened by a low transmission of the nanohole; (ii) the metal screen in which SHR is made ensures an efficient heat removal by the metal film, which, in turn, ensures the stability of the nanostructure to high-intensity radiation, making it possible to realize highly efficient nonlinear optical transformations [2]; (iii) at high intensities of the excitation field, an increase in the temperature of nanostructures does not cause a decrease in the Q factor of the plasmon resonance (resistive heating losses), because the metal film of the SHR efficiently removes heat [2]; (iv) the polarizability of a nanorod is higher than for a nanohole [3], therefore, the use of nanorods ensures a high optical nonlinearity of SHR nanostructures. II. NONLINEAR OPTICAL PROPERTIES OF A SINGLE SHR NANOSTRUCTUREAs a material for the creation of an SHR, we used aluminum. Investigations of SHRs were performed using radiation at a wavelength of 15...

“…In practice, the laser beam intensity at the fundamental frequency is limited by a value of ~10 10 W cm -2 . The record values of harmonic generation efficiency are on the order of ~10 -6 [29,34,36], which, at first glance, seems to be very low. However, one must also take into account the extremely small nanostructure volume with which laser radiation interacts.…”

“…It was demonstrated in [34] that, controlling the nanostructure geometry, one can control the character of its nonlinear optical interaction with laser radiation. For example, the formation of a nanostructure with roughness having a characteristic size of about 10 nm may leads to dominance of the individual-electron dynamics; as a consequence, nonlin-Third harmonic generation in the short-wavelength UV range by a single plasmonic nanostructure ear optical interaction manifests itself as multiphoton luminescence.…”

The nonlinear optical interaction of laser radiation with nanostructures formed in gold and aluminium nanofilms has been experimentally studied. It is shown that, despite the high susceptibility c 3 of aluminium in comparison with gold, the third-harmonic generation efficiency at a wavelength of 260 nm is much higher for the nanostructures formed in a gold nanofilm because of the efficient excitation of a localised plasmon resonance at the fundamental frequency.
