Abstract

A hybrid amplifier consisting of one stage of Erbium Doped Fiber Amplifier and two stages of RAMAN amplifiers is constructed. Two RAMAN fibers are cascaded in series to suppress the intensity noise due to double Rayleigh scattering. Backward pumping is applied at all stages in order to increase the gain of Erbium Doped Fiber Amplifier and to decrease the polarization dependent gain of Raman fiber amplifier. Gain Flattening is achieved for the entire C-band and L-band. The simulation results showed that the hybrid amplifier has the average Gain of more than 24 decibels in the wavelength range between 1530 and 1605 nanometers, with the Noise Figure of less than 6 decibels. The Gain of the Erbium Doped Fiber Amplifier and RAMAN was optimized to minimize the ripple value as low as 0.7 decibels with an output power of 14.076 decibel-milli.
