Magnetic and electric hotspots with silicon nanodimers.
The study of the resonant behavior of silicon nanostructures provides a new route for achieving efficient control of both electric and magnetic components of light. We demonstrate experimentally and numerically that enhancement of localized electric and magnetic fields can be achieved in a silicon nanodimer. For the first time, we experimentally observe hotspots of the magnetic field at visible...
متن کاملThird harmonic generation from mid-IR to near-IR regions in a phase-matched silicon-silicon-nanocrystal hybrid plasmonic waveguide.
The conversion efficiency of third harmonic generation (THG) from mid-IR (3600 nm) to near-IR (1200 nm) regions in a silicon-silicon-nanocrystal hybrid plasmonic waveguide (SSHPW) was calculated. The required modal phase-matching condition (PMC) between the 0-th mode at fundamental wave (FW) and the 2-nd mode at third harmonic (TH) is achieved by carefully designing the waveguide geometry. Bene...
متن کاملVisible quantum plasmonics from metallic nanodimers
We report theoretical evidence that bulk nonlinear materials weakly interacting with highly localized plasmonic modes in ultra-sub-wavelength metallic nanostructures can lead to nonlinear effects at the single plasmon level in the visible range. In particular, the two-plasmon interaction energy in such systems is numerically estimated to be comparable with the typical plasmon linewidths. Locali...
متن کاملDispersion in the anisotropy of optical third-harmonic generation in silicon.
We present what are to our knowledge the first theoretical and experimental results for dispersion in the anisotropy (sigma) of chi?((3)) associated with optical third-harmonic generation in Si. The theory is based on a full empirical tight binding band-structure calculation, and the results agree well with our measurements for 0.72 microm < lambda < 1.9 microm. The calculated low-frequency lim...
متن کاملNonlinear Harmonic Radiation from a Visible
Scientists from the University of California, Los Angeles, Brookhaven National Laboratory, Stanford Linear Accelerator Center and Lawrence Livermore National Laboratory have demonstrated for the first time the feasibility of using nonlinear harmonic self-amplified spontaneous emission (SASE) free electron laser (FEL) radiation to produce coherent, femtosecond x-rays. Nonlinear harmonic radiatio...
