| Abstract: |
When designing a multimode fiber system (MFS) one should take into consideration the mode-dependent properties of the components of the system. Lack of a design tool for fiber-optics netowrks makes the problem more difficult. However, one can describe a MFS using mode dependent matrices for each component of the system and obtain the system response as a product of these matrices and the input vectors. This method has been used by Evers to characterize couplers and connectors, and by Mickelson, et al for fusion splices and microbends. To our knowledge, there exist no work on transmission matrices for fibers, but only mode dependent attenuation measurements. The purpose of this paper is to give an accurate measurement technique to obtain the transmission matrix for arbitrary fiber optic connectors attached by multimode fibers, and apply these techniques to various connector/fiber combinations. |
