Abstract

Optical radiation emitted from a metal-coated fiber tip apex when it emerges from a liquid into the air was measured. A strong enhancement of the output radiation and its strong dependence on the relative position of the tip to a liquid surface were observed. This phenomenon permits in situ recording of nanometric vibrations of the liquid and provides a basis for development of various ultrasensitive vibration detecting sensors.

Sketch of the experimental setup. The cuvette, filled with glycerin, is attached to the piezostage, which is driven by a computer, while the position of the optical fiber is fixed. Transmitted radiation is detected by a p-i-n photodiode with an amplifier.
