Abstract :
We analyze the system performance of gain-saturated semiconductor optical amplifier (SOA)-based all-optical wavelength shifting with respect to its dynamic characteristics. When considering the risetime, contrast ratio and intersymbol interference, we find that there exists an optimal probe power and wavelength for high-speed wavelength shifting which reduces the power penalty by 3 dB. The minimum power penalties for the data rates of 10 and 20 Gb/s are 25 and 5 dB, respectively.<>
