摘　　要：提出了一种新型的双区DFB激光器件,对该器件产生自脉动效应的机理给出了理论分析,并以该器件作为光时钟恢复模块,对它的特性进行了数值模拟.基于该器件的光时钟恢复模块同原有的双区DFB激光器相比,具有自脉动频率高、调谐范围大的优点;同原有的多区DFB激光器件相比,具有结构简单等优点.In this paper,we have proposed a new tow-section DFB laser device.We have theoretically analyzed the mechanism of self-pulsation and given numerical simulation of the device as a time recovery module.Compare to two-section DFB lasers,it has the advantage of high speed self-pulsation and large tuning;Compare to multi-section DFB lasers,it has the advantage of simple structure.
