| Outline of Final Research Achievements |
Interaction of light with metal sub-wavelength structures has revealed new properties of light, such as light ability to pass through an array of nanoholes. Strong light confinement on the metal structures in the form of a plasmon resonance was found to be at the origin of this far field property. The optical properties of plasmonic structures have been used to monitor changes in their physical, chemical, and biological environments. The detection of this response in the far field is governed by the near-field properties of plasmon resonances. The micro integration on chips of these structures is difficult because of the far field readout. Thus, structures that form an electrical micro-circuit and directly monitor the optical near-field variation without resorting to far-field optical detection would be more desirable. Here, we demonstrate an electronically readable photocapacitor based on a plasmonic nanochannel structure with high spectral resolution and large impedance modulation.
