摘要	The experimental detection of high-frequency self-pulsation has been possible so far only in DFB lasers with at least one unbloomed facet. With facets produced by cleavage, the resultant phase position is an individual and technically uncontrollable factor for each DFB laser. It has so far been necessary, therefore, to select components in order to obtain lasers with a suitable pulsation characteristics. In a self-pulsing multi-section laser having two DFB sections, a Fabry-Perot-like resonator formed from two reflectors and a spacer is integrated into the multi-section laser and optically coupled to at least one DFB section. The spacer has a similar layer structure to the adjacent DFB sections (D1 and D2) but not DFB grid and takes the form of a control section operable electrically separated from the DFB sections. Selection is unnecessary. The self-pulsing two-section DFB laser of the invention with an integrated control section is suitable for optical beat regeneration in high-rate communication systems.
其他摘要	到目前为止，只有在具有至少一个未发光小平面的DFB激光器中才能实现高频自脉动的实验检测。对于通过解理产生的小平面，所得到的相位位置是每个DFB激光器的个体和技术上不可控制的因素。因此，迄今为止必须选择元件以获得具有合适脉动特性的激光器。在具有两个DFB部分的自脉冲多部分激光器中，由两个反射器和间隔物形成的法布里 - 珀罗状谐振器被集成到多部分激光器中并且光学耦合到至少一个DFB部分。间隔物具有与相邻DFB部分（D1和D2）类似的层结构，但不具有DFB栅格，并且采用可操作地与DFB部分电隔离的控制部分的形式。选择是不必要的。具有集成控制部分的本发明的自脉冲双截面DFB激光器适用于高速通信系统中的光学节拍再生。
