基于GT-SOA偏振旋转效应的全光缓存器及波长转换的研究
|
摘要
全光网可以使整个网络对光信号透明,使我们能够有效地利用有限的网络资源。将全光缓存和全光波长转换有机结合,可以很好地解决冲突问题,对全光网的发展起重要的作用。本文对基于GT-SOA偏振旋转效应的全光缓存器以及波长转换器进行了研究。
论文阐述了半导体光放大器的基本理论并对其进行了数值仿真。其中主要包括了载流子浓度在SOA轴向长度上的分布情况和增益受光功率的影响,以及光脉冲个数和光脉冲速率对载流子浓度和输出光功率的影响。
对于全光缓存系统,我们研究了：缓存时间与光纤环长的关系,模式间相位差对偏振态的影响,系统所采用的模型以及该系统的缓存原理。仿真分析了通过SOA后模式间相移与控制光功率、注入电流的关系；利用邦加球对信号光的偏振态进行了分析；对光缓存系统的关键部分—基于此效应的光开关进行了仿真研究。
针对GT-SOA中的非线性偏振旋转效应实现1310nm-1550nm的波长转换方法,提出了增加辅助光以改善其波长转换性能的方案,分析了辅助光对载流子恢复时间的影响以及全光波长转换的特性；针对速率分别为20Gbit/s和30Gbit/s的输入信号仿真分析了探测光模式间的相位差和转换光波形,以及信号光功率、电流和辅助光功率对转换光消光比的影响。
All-optical networks can make the whole networks transparent for the optical signal, and improve the utilization rate of cyber source. The settlement of the conflict and the development of the all-optical networks will be accelerate if we combine all-optical buffer and wavelength converter. This thesis research the all-optical buffer and all-optical wavelength converter based on the polarization rotation in GT-SOA.
We expound the SOA's basic principle and make the simulation analysis in this thesis. We analyze the variance of carrier density in the SOA's length, the gain's change with signal power, and the influence of the pulse number and pulse rate to carrier density and light power.
The all-optical buffer based on the polarization rotation in GT-SOA is analyzed, including the relationship between the buffer time and the length of the fiber loop, the influence of the phase shift between TE and TM mode on the polarization state, and the principle of this system. We simulate the variation of phase shift between TE and TM mode with the control light power and the injected current, and we simulate the difference of the polarization state by the Poincare sphere. At last we discuss the buffer-optical switch based on polarization rotation as the key component in the system.
We propose an all optical 1310 to 1550nm wavelength conversion system based on nonlinear polarization rotation in GT-SOA which adds the assistant light to improve the property of the converted light. We analyze the influence of assistant light to carrier density, and we discuss the wavelength conversion and simulate the phase shift between TE and TM mode and the converted light for 20Gbit/s and 30Gbit/s signals. We analyze the influence of the input signal power, injected current and the assistant light power on the extinction ratio of the converted light.
