Abstract

The purpose of this article is to show that it is possible to make efficient optical tweezers using a properly modified single mode fiber. By using a micro-lens, fabricated directly on the cleaved end of an optical fiber, by a focused ion beam milling process, efficient optical tweezers can be obtained. A 30 keV focused Ga⁺ ion beam is used to mill a continuous profile microstructure. An axicon with 10 μm diameters and 5 μm high is fabricated, which permits the transformation of a Gaussian mode in a Bessel mode beam. This particular mode was used to form an optical trap. Measures of the propagation profile and of the trapping effect will be discussed.
