Plasmon Enhanced Near-field Probe

Plasmonics Image

The above image illustrates our modeling and fabrication capabilities.  It is a plasmon-enhanced near-field probe used in our long travel near-field scanning optical microscope (NSOM).


  • Wave guide coupled plasmon resonator for high transmission with minimal absorption in metal 
  • Metal post for AFM level resolution (U. S. patent # 7,250,598)
  • Applications in microscopy, tip enhanced RAMAN, and data storage
  • Concept probe on an optical fiber with FEM power flow and SEM of a fabricated test structure
  • Direct fabrication on optical fibers
  • Finite element model of probe-sample interaction
