Abstract
For system-optimizations beyond the coupling-length of plastic optical fibers, the excitation conditions become very important, because the coupling between light source and fiber influences the attenuation and bandwidth of the system. A modified measurement technique for mode selection in plastic optical fibers with step-index profiles is introduced. For testing and characterization of these fibers, low and high order meridional rays are used, excited by changing the excitation angle of the incoming light beam, which is either a focussed laser beam or an endface of an excitation fiber. Measurement results are presented, including the separation of the measured high excess losses into two components.
