    "abstract": "Using exact three-dimensional vectorial simulations of radiation coupling\ninto uncoated dielectric fiber probes, we calculate amplitude transfer\nfunctions for conical single-mode fiber tips at the light wavelength of 633 nm.\nThe coupling efficiency of glass fiber tips is determined in a wide range of\nspatial frequencies of the incident radiation for opening angles varying from\n30 to 120 degrees. The resolution in near-field imaging with these tips is\nconsidered for field distributions limited in both direct and spatial-frequency\nspace. The characteristics of the transfer functions describing the relation\nbetween probed optical fields and near-field images are analyzed in detail. The\nimportance of utilizing a perfectly sharp tip is also examined.",
