| 摘 要： | 采用国产普通折射率耦合型两段式ＤＦＢ半导体激光器进行了波长调谐实验研究，实验结果表明，通过分别调节激光器两段的工作电流，不仅可以使器件单模工作，而且还能进行波长调谐。波长调谐范围为６．２ｎｍ，连续波长调谐范围为０．９ｎｍ。

| Abstract: | The wavelength tuning experiments have been made by use of the ordinary index-coupled two-segment DFB semiconductor lasers. The single-mode oscillation and wavelength tunability have been realized by changing currents of two segments. A 6.2nm tuning range and a continous wavelength tuning range of 0. 9nm have been observed. |
