We demonstrate scanning near-field optical microscopy with a spatial resolution below 100 nm by using broadband synchrotron radiation in the infrared range provided by the Metrology Light Source. This approach opens up the possibility to perform Fourier transform infrared spectroscopy on a nanoscale.
Surface Brillouin spectroscopy was applied to characterise the dynamics of surface acoustic waves in a silicon-based nanocomposite. The propagation velocities of Rayleigh phonons and their anisotropy in silicon support (111) loaded with a nanosized nickel island structure were determined. Deposition of a 2D nickel nanostructure on silicon substrate leads to the appearance of new peaks in the Brillouin...
In this paper, we show that this large-area, high-coverage method for the fabrication of optical split-ring resonator gold metamaterials allows for substantial tunability of the structural dimensions and their respective resonance frequencies. We demonstrate excellent agreement of the adjustable parameters, such as the inner and outer ring diameter, the opening gap angle, as well as the metal thickness...
We present experimental results on the optical and magnetic properties of transition metal films with sub-wavelength hole arrays. Magneto-optic measurements show a spectacular magneto-optic response at wavelengths where surface plasmon-polaritons are supported by the structure.
