Near-field optical probe based on the fiber Fabry-Perot interferometer with protruding evanescent light source

摘要

We studied numerically and experimentally the possibility of the development of a novel probe based on the fiber Fabry-Perot interferometer with an evanescent light source protruding directly toward the sample. It was shown that such probe provides a spatial resolution ~λ/40 for λ=1550 nm. The fabrication process of such a probe is described in detail.
