Research on the influence of alignment error on coupling efficiency and beam quality for Gaussian beam to multimode fiber
The effect of alignment error on the coupling efficiency and beam quality of a Gaussian beam coupled into a large-core multimode fiber is studied in this paper. The equations for evaluating the effect of alignment error on the coupling efficiency are derived separately, and verified with the method...
