Abstract

Many possibilities are offered to analyze the field in tapered fibers. We have used in this work the bpm method and the coupled-mode theory for a conical fiber. In the second case, it is shown by a length-scale criterion that some geometries should provide a good efficiency. The comparison between the quasi 3D numerical simulation and the local mode method is also performed. The complete resolution procedure is then dependent on certain essential approximations and simplifying hypothesis.
