Abstract
A novel kind of optical fiber Raman amplifiers using time-division-multiplexed (TDM) pumping is analyzed. The equations governing the evolution of the pumps and signals are presented for both TDM forward and TDM backward pumping. Simulation results show that the performance in gain profile and ASE noise figure can be effectively improved. The optimal TDM pump repetition rates are between 2 and 8 MHz.
