| Abstract: | Theoretical model for bit error rate performance analysis of XGM Wavelength converter used in a communication system bosed on semiconductor optical amplifier (SOA) is developed. Carrier consumption due to Amplified Spontaneous Emission is the first time considered in solving carrier rate equation. It is shown from numerical calculation for wavelength conversion in 10Gbit/s bitrates, 1550nm window that bit error performance is simultaneous affected by extinction ratio, conversion efficiency and noise. For special structure parameters of SOA, there exist optimal probe power, average pump power and wavelength conversion span for wavelength conversion. So that must be the best way to optimize parameters of wavelength converters by analyzing bit error performance. |
