Abstract
Apparatus for electrical and optical nanoprobing at resolution beyond optical diffraction limit. Navigation microscope is configured for navigation to a region of interest. A probe spatial positioner supports a fork and an oscillating piezotube is attached to the free end of the fork and provides an output indicating of a distance to the sample. A single-mode optical fiber having a near-field transducer formed at an end thereof is attached to the oscillating piezotube such that the near-field transducer extends below the oscillating piezotube towards the sample. A photodetector is positioned to detect photons collected from the sample. The near-field transducer may be formed as a tapered section formed at the end of the single-mode optical fiber, a metallic coating formed at a tip of the tapered section, and an aperture formed in the metallic coating so as to expose the tip of the tapered section through the metallic coating.
