Summary form only given. The optical response of nanostructured semiconductors around the bandgap is dominated by the properties of excitons in interface potentials fluctuating: on a mesoscopic length scale. On this length scale, scanning near-field optical microscopy (SNOM) extents the optical resolution to a fraction of the wavelength of light. The results of a finite difference time domain evaluation...
Summary form only given. The enhancement of the light and matter interaction that can be obtained in periodic structures such as 1D photonic crystals or Fabry-Perot microcavities might be best used when the interaction considered is nonlinear. It has been theoretically shown that changes in the effective index of refraction of a dielectric material leading to large changes in reflection or transmission,...
