Campanile Near-Field Probes are one of the most promising near-field probes today.

The “campanile” near-field probe was originally invented by a group of scientists at Lawrence Berkeley National Laboratory. The innovative design won the prestigious R&D 100 award in 2013.

The team between HighRI Optics, Inc (formally a part of aBeam Technologies, Inc) and Nanofabrication Facility at the Molecular Foundry, Lawrence Berkeley National Laboratory has recently developed fiber nanoimprint based process for volume production of campanile near-field probes.

Main features of Campanile near-field probes:

  • a strong local electromagnetic field enhancement
  • efficient far-field to near-field coupling
  • nanoscale spatial resolution, background-free operation
  • broadband photon-plasmon coupling and access to polarization properties

The probes will come in two platforms; Fiber-based & Cantilever-based campanile probes.
