摘要
为改善SOA-MZI-XPM型AOWC的性能,对影响AOWC输出特性的因素进行深入研究,其中重点对输入信号功率、光信号的偏振态和光耦合器的耦合系数三个因素的影响进行讨论。在信号速率为10Gb/s的波长转换实验中,采用合适的光信号输入功率和合理的偏振控制,消除了输出信号中的杂散频率,使输出信号的Q因子有了较大提高,改善了波长转换器的转换特性。
In order to improve the performance of AOWC based on SOA-MZI-XPM, this paper studies the determinants of output characteristics, especially the factors such as the power of the input signals,the polarization of light signal and the coupling coefficient of the optical coupler which affect the AOWC mostly. In the wavelength conversion experiment under the conditions of the signal transmission rate of 10Gb/s, using proper optical inputting power and reasonable polarization control, this experiment eliminates the spurious frequencies in the output signal through which the Q factor and the conversion characteristics has been greatly improved.
