摘要
为了提高光网络中波长资源的使用效率, 利用光纤中瞬态受激拉曼散射效应分析理论, 设计了一种基于掺锗光子晶体光纤的可调谐四通道波长转换器。由于受激拉曼散射效应的增益随信号光与探测光波长之间的频移量变化, 波长转换器各个转换信道波长可由探测光波长调谐。分析了泵浦信号光输入功率对多波长转换器性能的影响, 结果表明: 随着输入泵浦功率的增大, 多路波长转换器的转换性能更好。用OptiSystem对四通道可调谐波长转换进行仿真, 结果表明: 所设计的波长转换器能够同时实现四通道波长转换, 各信道波长可在1511~1569nm进行调谐。
Abstract
In order to improve the service efficiency of the wavelength resources in the optical network, a tunable four-channel wavelength converter based on Ge-doped photonic crystal fiber was proposed by using the theory of transient stimulated Raman scattering in optical fiber. Since the gain of the stimulated Raman scattering effect will change with the frequency shift between the signal light and the probe light wavelength, the wavelength of each conversion channel can be tuned by controlling the wavelength of the probe light. The influence of pump input power on the performance of multi-wavelength converter was analyzed, and the results show that the conversion performance of the multi-channel converter is better with the increase of the input pump power. The simulation was calculated by OptiSystem with four-channel tunable probe signals. Simulation results show that the four-channel tunable wavelength converter can simultaneously achieve four-channel wavelength conversion, each channel wavelength can be tuned from 1511nm to 1569nm.
