| Research Abstract |
Mid-infrared light provides powerful tools in probing microscopic molecular structures and in exciting molecular vibrations with high selectivity. Field enhancement in mid-infrared range, therefore, may help developing schemes of analyzing conformations of macromolecules and controlling molecular motions/reactions. In this project, we investigate metal nano-structures which bring about resonant enhancement of the mid-infrared electromagnetic waves.By transmission spectroscopy and the electromagnetic field analyses, the spectral/temporal responses of the enhanced near-fields are clarified. The spatial distribution of the enhanced near-field is measured by using the scanning-type near-field optical microscopy working in the mid-infrared range. We also investigate by numerical simulations the degree of freedom in shaping the temporal waveform of the enhanced near-field.
