双折射光纤受激喇曼散射模式的实验研究

Experimental Analyses on Stimulated Rama Scattering Mode in Single-mode Birefrigent Opticl Fiber

本文在实验上对三种不同结构的石英系双折射单模光纤中受激喇文散射传输模式进行了研究。给出了测试装置、SRS光谱和各级斯托克斯线模式尿片。其结果与圆芯多模梯度折射率光纤完全不同。受激喇更散射的光众尺寸基本不变、而且具有以高阶模传输特点。这些结果在国内外尚未见报道。

Stimutatal Raman scatterlng (SRS) transmisslon mode in highly eiliptital-core optiCal fiberof three dchrent structures are expehoentally researched. The measuring setup,SRS spetrum and pho-tographe of stockes mode are given. The oteerved phenomena are completoly different from those oncircuklar-core greded-index optical fiber the bo stses of SRS remain constant and SRS ttansmits withthe characteristics of higher-order mode.
