The combination of nonlinear optics and nanotechnology is an extremely rich scientific domain yet widely unexplored. We present here a review of recent optical investigations on noncentrosymmetric oxide nanoparticles with a large χ (2) response, often referred to as harmonic nanoparticles (HNPs). HNPs feature a series of properties which distinguish them from other photonics nanoprobes (quantum dots, up-conversion nanoparticles, noble metal particles). HNPs emission is inherently nonlinear and based on the efficient generation of harmonics as opposed to fluorescence or surface plasmon scattering. In addition, the fully coherent signal emitted by HNPs together with their polarization sensitive response and absence of resonant interaction make them appealing for several applications ranging from multi-photon (infrared) microscopy and holography, to cell tracking and sensing.

“…These advantages make NPs more cost effective and easier to handle than their bulk crystal counterpart. The SH emission from single nonlinear NPs [13][14][15][16][17][18] and nanotips 19 interacting with ultrafast pulses has recently been detected and studied.

Phase control of femtosecond pulses on the nanoscale using second harmonic nanoparticles

et al. 2014

Investigations of ultrafast processes occurring on the nanoscale require a combination of femtosecond pulses and nanometer spatial resolution. However, controlling femtosecond pulses with nanometer accuracy is very challenging, as the limitations imposed both by dispersive optics on the time duration of a pulse and by the spatial diffraction limit on the focusing of light must be overcome simultaneously. In this paper, we provide a universal method that allows full femtosecond pulse control in subdiffraction-limited areas. We achieve this aim by exploiting the intrinsic coherence of the second harmonic emission from a single nonlinear nanoparticle of deep subwavelength dimensions. The method is proven to be highly sensitive, easy to use, quick, robust and versatile. This approach allows measurements of minimal phase distortions and the delivery of tunable higher harmonic light in a nanometric volume. Moreover, the method is shown to be compatible with a wide range of particle sizes, shapes and materials, allowing easy optimization for any given sample. This method will facilitate the investigation of light-matter interactions on the femtosecond-nanometer level in various areas of scientific study.

“…Additionally, the broadband excitation corresponding to a 10-fs pulse offers the possibility of spectral manipulation for coherent control (Warren et al, 1993;Weiner, 2000) of two-photon absorption and non-resonant second harmonic generation (Broers et al, 1992;Meshulach & Silberberg, 1998;Wnuk & Radzewicz, 2007). While it has been recently shown that a SHG-active nanoparticle of a size about a few hundreds of nanometers can be used for pulse detection in a nanoscopic version of the FROG technique (Extermann et al, 2008), the effects of manipulation of the excitation beam on SHG emission, i.e.,decreasing the time duration of a precompensated pulse as well as structuring its broadband spectrum, have not yet been investigated at the single nanoparticle level with a size well below the wavelength of light. Moreover in this size range phase matching conditions are automatically fulfilled, improving the coherent emission.…”
