Optimal Launch States for the Measurement of Principal Modes in Optical Fibers
Optimal Launch States for the Measurement of Principal Modes in Optical Fibers
Modal dispersion characterization of multimode optical fibers can be performed using the recently-proposed mode-dependent signal delay method. This method consists of sending optical pulses using different combinations of modes though the multimode optical fiber and measuring the mode group delay at the fiber output. From these measurements, it is possible …
