利用相移测量了单模As2 S3 光纤在 1 5 5 μm附近的色散。测量结果显示 ,As2 S3 光纤的材料色散为- 39ps/ (km·nm)。特殊的色散特性 ,预示了硫系光纤及其器件广阔的应用前景。
The dispersion of single-mode As2 S3 fiber near 1 55 μm was measured by phase shift. The measurement results show that the material dispersion of As2 S3 fiber is -39 ps / (km · nm). The special dispersion characteristic indicates the broad application prospect of sulfur-based optical fiber and its components.
