Paper Abstract

Many possibilities are offered to compute field. We have used in this work the bpm method and the local mode method for a conical fiber. In the second case, it is shown by a length-scale criterion that some geometry should provide a good efficiency. We examine the fiber end and show that an appropriate lens form makes it possible to adapt the power distribution between the optical fiber and the photodiode. Some taper shapes are suggested and the model accuracy is discussed according to the nature of the decrease criterion. We obtain in this case an assessment along this guide that is optimized. The comparison of this results with the quasi 3D numerical simulation of the guided optical propagation is also performed.
