英文摘要：
The design of a 40GHz broadband light source is presented. Key technologies of the light source are developed,including techniques for stabilizing the devices and compensating the frequency response distortion. A 40GHz broadband light source based on a LiNbO3 optical modulator has been successfully manufactured. Experiments and tests show that the light source can be used not only for small signal frequency response measurement systems, but also for large signal SDH/SONET transmission test systems.
