| 摘 要： | 由于拉曼增益效应,斯托克斯(Stokes)光可以引起频率上移信号光的损耗。通过对描述拉曼效应的耦合功率微分方程组的仿真计算,得到了衰减受传输距离和泵浦光强的影响关系,并从理论上给予了分析说明。同时对前人的实验观察结果进行了验证,理论与实验达到了很好的吻合,提出了利用拉曼增益效应进行光信号处理的可行性。最后指出了利用拉曼效应的优点,并展望了其广阔的应用前景。

| Abstract: | Optical signal at Stokes frequency producing the attenuation of the signal at higher frequency is studied in this paper.By simulating the couple power differential equations,the relations of the signal's attenuation with pump power and distance are analyzed numerically and theoretically.The good accordance between our solutions and the former researcher's experimental observations proves the feasibility that signal processing can be realized by pure optical method.The advantages and broad applications are also illustrated. |
