Abstract
A system is provided for forming an end of an optical fiber into a lens, which produces a lensed fiber having an especially smooth lens surface and high strength near the intersection of the lens and the rest of the fiber. A lens is formed by establishing a pair of electrodes on opposite sides of a fiber end portion and establishing an arc between the electrode tips for a sufficient current and time to melt the fiber end portion into a lens, with the arc being repeatedly terminated and restarted at a rate of thousands of times per second.
