ABSTRACT:
A process is described for etching a tapered point on a cylindrically symmetric body using an inert liquid layer on top of the etching solution. The process is extremely useful for etching tapered points on optical fibers prior to melt-back to form a small lens to couple light from laser to optical fiber. The process produces excellent tapered points rapidly and reproducibly with a minimum of operator attention and without etch marks above the taper.
