“…In a conclusion, we have realized giant optical nonlinearity of a single nanostructure which we call a split hole resonator: (i) it allows a record high efficiency of generation of the third harmonic of radiation from a single nanostructure; (ii) it allows a record high efficiency of generation of multiphoton luminescence; (iii) it makes it possible to realize a nanolocalized radiation source with a spatial localization of about λ/15. We also note that it is possible to further increase the operation efficiency of SHR nanostructures using microcavities based on photonic crystals [28,33,34] or active hyperbolic metamaterials [35].…”

Giant optical nonlinearity of a single plasmonic nanostructure

We realize giant optical nonlinearity of a single plasmonic nanostructure which we call a split hole resonator (SHR). The SHR is the marriage of two basic elements of nanoplasmonics, a nanohole and a nanorod. A peak field intensity in the SHR occurs at the single tip of the nanorod inside the nanohole. The peak field is much stronger than those of the nanorod and nanohole, because the SHR field involves contributions from the following two field-enhancement mechanisms: (1) the excitation of surface plasmon resonances and (2) the lightning-rod effect. Here, we demonstrate the use of the SHR as a highly efficient nonlinear optical element for: (i) the generation of the third harmonic from a single SHR; (ii) the excitation of intense multiphoton luminescence from a single SHR.

“…The radiation of the localised light source is amplified at the resonance wavelength of the microcavity, whereas radiation at other wavelengths is attenuated. We have demonstrated the control over the spectrum and efficiency of the nanolocalised light source [32,33]. The microcavity was formed by an optically thick gold layer (200 nm) and twelve alternating dielectric layers of TiO 2 and MgF 2 of thickness l/4n ( l = 730 nm) differing in the refractive index.…”

Possible spatial localisation of femtosecond laser radiation to the size on the order of 50 nm is studied. An approach to femtosecond laser radiation localisation in the nanometre scale is based on the use of nonlinear processes in metal nanostructures. It is shown that the extremely high third-order optical susceptibility of metal nanostructures and strong plasmon resonances give a possibility to realise an efficient nanolocalised source of radiation at the third harmonic frequency and a wideband femtosecond radiation based on metal photoluminescence.

“…From the viewpoint of practical applications, the case of a conducting metal as a PC-adjoining medium seems to be the most interesting. In this case, not only is surface localization of the electromagnetic field possible, but also a considerable enhancement of the field amplitude in the PC/metal-nanofilm system [7,11,12]. In addition, the metal nanofilm on the surface of the PC makes it possible to perform surface nanostructuring in it [11,12].…”

Optical Tamm state on a femtosecond time scale

2013

In this work, we investigated the temporal dynamics of the optical Tamm state (OTS) that arises at the interface between a one-dimensional photonic crystal and a gold nanofilm. The temporal dynamics was measured by two methods: (1) the spectral method, which is based on the analysis of the spectral composition of reflected light, and (2) the probe method, i.e., by embedding an inertialess probe into the OTS mode. It was found that the temporal dynamics of OTS formation is determined by the quality factor of the photonic-crystal/nanofilm microcavity with a characteristic time of OTS formation in the range of 100 to 300 fs.
