At the same time, the line width measurement methods are emphasized in this thesis. When we use homodyne method, the spectral line-width of ECSL is 20 KHz. Therefore, Lasers which have working stability can be continuously exported.

When the external optical feedback is intermediate, the peak photon number of the ECSL behaves single period, multi-period or chaos for different modulation index.

当外部光反馈处于中度反馈时，当调制深度取不同值时，ECSL的光子数呈现单周期、多周期甚至混沌现象。

Based on the ECSL which has narrow line-width and unique modulation characteristic, a dual-wavelength output is obtained by means of fiber delay technique.
