Probes for a scanning near-field optical microscope on the base single-mode fiber

Probes for a scanning near-field optical microscope on the base a single-mode adiabatically tapered optical fiber have been fabricated by the chemical etching only. The transmission coefficient of light in this probes is 2-3 order magnitude higher than that of mechanical pulled fiber probes. The reason of this effect is explained. Probe of the scanning near-field optical microscope on the base microstrip line is proposed.
