Probes for a scanning near-field optical microscope on the base tapered single-mode optical 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 fibres probes. The probes may be used for green (lambda=0.48-0.55 mum), red (0.60-0.68 mum) and near infrared (0.78-1.05 mum) wavelength ranges the reason of this effect is explained. Probe of the scanning near-field optical microscope on the base microstrip line is proposed
