Paper Abstract

In this paper near-field distributions of nanometric apertures, the uncoated and metal-coated fiber-optic probes used in near-field scanning optical microscope are characterized by the method of finite-difference time- domain. Moreover, to give a clear view of the influence of parameters, say, the taper angle ((alpha) ), the aperture diameter (d), the refractive index of the fiber-optic (n) and the sample (ns), the tip-sample separation (z), on the throughput of metal-coated fiber-optic probes, we investigated it in detail.
