Study of recombination's effect oncharacteristic and self -phase modulation in semiconductor optical amplifier


This paper presents a detailed simulation study of the spontaneous and auger recombination on amplification characteristic and self -phase modulation in travelling- wave (TW) semiconductor optical amplifier (SOAs). The effect is studied on the gain, output signal power, nonlinear phase shift spectrum, and shape of amplified pulse at a range of drive currents. For small value of recombination, gain and output signal power were large, and the peak spectrum shifts more to longer wavelengths.
