Abstract

In this paper we describe a new fiber lensing technique in which an index-matched microlens is fabricated on the tip of a single-mode fiber. The lens is formed by etching the fiber until only a "whisker" of pure core material remains. This whisker then is cut and arc melted back to form a lens of proper radius for optimal laser-to-single-mode fiber coupling. High average coupling efficiencies of greater than 45% (best value 61%) have been measured and will be reported. The ability to etch many fibers at the same time with reproducible results indicates that the technique is compatible with batch processing. We will explain the lens formation technique in detail and describe the conditions necessary to obtain optical coupling efficiencies. Finally, the coupling sensitivity to lateral misalignment between laser and fiber will be presented.
