title: Cavity-based Fabry-Perot probe with protruding subwavelength aperture.
abstract: We investigate numerically and experimentally the possibility of development of a cavity-based probe for near-field optical microscopy systems based on a fiber Fabry-Perot interferometer with a subwavelength protruding aperture. It was shown that the probe provides a spatial resolution of no worse than λ/37 for λ=1550 nm.
