Original Abstract

Near-field optical techniques are presently widely used to study various optical characteristics of transparent or opaque microscopic structures such as optical waveguides, photonic crystals, semiconductor junctions, nanostructured systems. To control a light-matter interaction at nanometer distance, structures guiding electromagnetic energy with lateral mode confinement below the diffraction limit of light are necessary. Tapered tiny optical fiber probe is a crucial part of the system, governs its resolution, and simultaneously could play role as light source, detector, or both. Therefore it must be protected against mechanical vibration, cracks, etc. For its accurate simulation, it is essential that its geometry is correctly described, especially when coupling to evanescent field is considered.
