ABSTRACTOptical amplifiers promise to revolutionize optical communication. Erbium-doped silica fiber amplifiers operating at 1.5 μm are now commercially available while the performance of devices using neodymium or praseodymium doped fiber in the 1.3 gtm telecommunications window are improving rapidly. This review discusses the importance of host material on amplifier characteristics.

Erbium Doped

According to the analytical expression for modal gain of few-mode erbium-doped fiber amplifiers (FM-EDFAs), we propose a method of measuring the absorption loss coefficients of few-mode signals in few-mode erbium-doped fibers (FM-EDFs) by extrapolating the mode–gain curve dependent on the average population inversion. The absorption loss coefficient of an FM-EDF was measured in our experimental platform and used to estimate the effective erbium-ion doping concentration. The feasibility of the extrapolation method was verified by simulation and comparison with the transmission method. Furthermore, the FM-EDFAs with high modal gain and low differential mode gain (DMG) could be optimized by adjusting the FM-EDF’s length and pump power. The analysis process presented here is very useful for the efficient design of FM-EDFAs from a practical point of view.
