我们报告什么是我们所知的第一个演示太赫兹率光脉冲产生的谐波被动锁模在分布式布拉格反射器激光二极管。沿着，随着基频重复率为38.8 GHz，我们观察到400-GHz，800-GHz，和1.54-THz的谐波，这取决于增益部分的偏置条件。1.54太赫兹脉冲的脉冲包络与从光谱的傅里叶变换的计算结果非常一致，表明输出脉冲是变换限制的。
We report what is to our knowledge the first demonstration of terahertz-rate optical pulse generation by harmonic passive mode locking in a distributed-Bragg-reflector laser diode. Along with the fundamental repetition rate of 38.8 GHz, we observed 400-GHz, 800-GHz, and 1.54-THz harmonics, depending on the bias condition of gain section. The pulse envelope for 1.54-THz pulses was in good agreement with a calculation from the Fourier transformation of the optical spectrum, indicating that the output pulses are transform limited.
