  • Publication number: 20180149972
    Abstract: Disclosed is a method of conducting chemical reactions below the diffraction limit. The method comprises providing a composition comprising or consisting of at least one photoenol, initiating a reaction which emanates from the photoenol at a selected site by irradiation with light of a first, photoenol-activating wavelength, and concurrently or thereafter, suppressing the reaction emanating from the photoenol in the immediate vicinity of the selected site by irradiation with light of a second, photoenol-deactivating wavelength which creates an interference pattern having an intensity minimum or zero intensity at the selected site.

  • Patent number: 9684221
    Abstract: Provided are systems and methods to generate single-cycle THz pulses from a few tens of nanometers thin layer of split ring resonators (SRRs) via optical rectification of femtosecond laser pulses. The emitted THz radiation, with a spectrum ranging from about 0.1 to 4 THz, arises exclusively from pumping the magnetic-dipole resonance of SRRs around 200 THz. This resonant enhancement, together with pump polarization dependence and power scaling of the THz emission, underpins the nonlinearity from optically induced circulating currents in SRRs, with a huge effective nonlinear susceptibility of 0.8×10?16 m2/V that far exceeds surface nonlinearities of both thin films and bulk organic/inorganic crystals and sheet nonlinearities of non-centrosymmetric materials such as ZnTe.
