Abstract
A simple and inexpensive method to couple light into a fiber and collect light from a fiber is essential to realize many new optical communications applications such as network interconnections, line status-monitoring systems, optical sensors, and signal-processing systems. We have recently demonstrated tire possibility of laser ablative chemical etching (LACE) of silica fibers to produce such fiber-optic taps.1-2 The previous techniques for fabrication of taps on fibers are not sufficiently easy, rapid, inexpensive, and reliable because they involve mechanical techniques such as macrobending, polishing, slicing, and deposition of dielectric mirrors in the fiber core, or epoxy attachment to the fiber core.
