摘　　要：提出了一种基于注入锁定分布反馈式(DFB)激光器的双波长差频微波/毫米波信号产生方案。方案利用正弦波光信号通过半导体光放大器(SOA)进行非线性展宽,产生高阶分量,然后注入到两个DFB激光器后进行锁定放大,产生频率连续可调的倍频信号。在实验中,注入的正弦波光信号频率为1.25GHz,得到20～40GHz频率范围内1.25GHz的任意自然数倍的连续可调微波信号,其最高倍频数为32。An approach to achieving continuously tunable microwave/millimeter-wave frequency multiplication signal based on injection locked dual-wavelength difference-frequency distributed feedback （DFB） laser is proposed. Wave optical signals are nonlinearly broaden by semiconductor optical amplifier （SOA）, and high-order components are generated. The sine wave optical signal is injected into two DFB laser and locked enlarge, then the continuously tunable frequency multiplication is generated. In the experiment, the injected sine wave optical signal frequency is 1.25 GHz, the continuously tunable microwave signal with any natural multiples of 1.25 GHz in the 20 -40 GHz frequency range is achieved, and the highest multiplier of 32.
