Research potential possibilities of estimating the basic mode transmission coefficient based on analysis overlapping of the radial distribution fields in discrete representation

In the article research potential possibilities of estimating the basic mode transmission coefficient based on analysis overlapping of the radial distribution fields in discrete representation. Considered the process of passage the fundamental LP01 mode, characterized by the simplest distribution field, through the connection of a pair of single-mode optical fibers, made with a certain radial mismatch with a scatter in the values а spot radius mode interacting modes. The results of experimental verification of the proposed method are presented, which have demonstrated the potential of its use.
