Paper Abstract

The performance of the alignment governs the quality of the optical communications. The active alignment methods search the position with highest optical power and connect fiber on this position. Thus, active method can adjust the connection for different properties on the fiber end-face. In the literatures, the methods for the multi-fiber alignment can increase the optical power summation of all fibers, but the results are not very accurate. This study used the numerical optimization methods, the gradient based and non-gradient based methods, for the optical component alignment, and discusses the performance on different optimization methods applied on multi-fiber alignment. There are two indexes used to judge the performances of different methods: the required time and the optical power. It is obvious that the gradient based methods can have the results with better optical power, and the non-gradient based methods are very fast to converge, but the optical powers are still very small comparing to the gradient based methods.
