Abstract

A novel fiber characterization technique is introduced that combines two holographic procedures for selective fiber-mode excitation and complete fiber-mode analysis. The fiber’s transmission matrix is constructed by directly measuring the response of the excited modes in terms of the entire guided mode spectrum. By applying a spatial multiplexing scheme for the modal decomposition, the transmission matrix is rapidly determinable, whereas the amount of needed measurements is proportional to the number of guided modes. Our technique characterizes the impact of the fiber on the mode signals and enables the investigation of underlying physical effects as well as signal correction schemes.
