Many new and intriguing phenomena occur in nanometer (10-9 m) scale that are of fundamental scientific interest. However it is difficult to study these phenomena using light, since we cannot focus light to such small dimensions with regular optical lenses due to a limitation imposed by diffraction of light. We study nanoscale properties by overcoming the diffraction limit.
Our research interests include:

  • Subwavelength-scale fundamental properties and spatial dynamics of surface plasmon polaritons
  • Plasmonic metamaterials
  • Near-field nanoscopy of novel correlated transition metal oxides and their interaction with plasmon resonances
  • Spectroscopic imaging of organic and inorganic semiconductors in the frequency range visible to THz
  • Bionanoparticles and nanobiotechnology
