| 摘 要： | 利用速率方程分析了转换信号光的频率啁啾,考虑到了外界注入信号光的放大.转换过程中,信号光的注入将会导致了光腔内载流子数发生变化,进而引起激光器输出频率的改变,产生啁啾.研究发现,较大的激光器注入电流可以有效地抑制频率啁啾,较高的注入信号光功率则可以在保证高转换信号消光比的同时抑制频率啁啾.

| Abstract: | The trequency chirp of the converted signal is analyzed by using the rate equation ,in addition the amplified input signal is considered. During the course of the conversion, the amount of carriers in laser cavity will be changed when signal light is injected. As a result, the frequency of the output signa light will be changed, and the chirp of frequency will occur. The results show that higher injected current can restrain the frequency chirp effectively, and higher input optical power can also do that , meanwhile, good extinction ratio is ensured. |
