The coexistence of different propagating modes inside an optical multi mode fiber (MMF) determines the properties of the emerging beam. Hence, detailed knowledge of the (transversal) modal content became essential to understand the underlying physical effects. Different approaches were applied to acquire knowledge about modal content of MMFs such as interferometry or M2 respectively S2 measurement. In this paper we present new results concerning the access to full field information of vector beams, emerging from two step-index LMA fibers (V -parameter 3.96 and 4.72, respectively). Thereby, the direct approachable measurement data consists in modally resolved information about polarization state, intermodal power distribution and intermodal phase delay. By means of the reconstructed field, "global" characterizations of the investigated beams, e.g., in form of the widespread beam propagation ratio M2, are possible.© (2010) COPYRIGHT SPIE--The International Society for Optical Engineering.
