对石英系单模保偏光纤中的受激拉曼散射传输模式进行了实验研究,测得三种不同截止频率的单模保偏光纤中受激拉曼散射光谱及其模式的分布,其结果与圆芯多模渐变折射率光纤中的受激拉曼散射模式分布完全不同：斯托克斯光谱的光斑尺寸基本不变;而且具有以高阶模传输的特点。这些结果在国内外尚未见报道。

The SRS propagation modes in single-mode polarization - maintaining optical fibers were experimentally studied. The SRS spectrum and mode profile of three different cut-off wavelength fibers were obtained and the experimental results were completely different from those in circal-core graded-index optical fibers. The size of SRS beam remains nearly constant and they were characterized by the propagation with higher order mode. These results have not be seen both home and abroad.
