New experimental studies on the effects of high hydrostatic pressure on highly birefringent optical fibers are presented. Using Rayleigh scattering, the effect of beat length modification in highly birefringent singlemode bow tie fibers under high pressure up to 100 MPa was investigated. The results indicate that the beat length decreases with pressure, with the mean coefficient of 1/L(B0)|dL(B)/dp| = 0.15%/MPa. A similar decrease of beat length was observed when uniaxial longitudinal stress was applied to the bow tie fiber. A more developed semiphenomenological interpretation of these experimental results is also presented in the paper.
本文介绍了关于高静水压力对高双折射光纤影响的新实验研究。利用瑞利散射，研究了高达100兆帕的高压下高双折射单模蝴蝶结光纤中拍长变化的影响。结果表明，拍长随压力减小，平均系数为1/L(B0)|dL(B)/dp| = 0.15%/MPa。当对蝴蝶结光纤施加单轴纵向应力时，也观察到了类似的拍长减小现象。本文还给出了对这些实验结果更完善的半唯象解释。
