介绍了一种基于单片集成双模反馈放大激光器(AFL)的线性啁啾微波波形发生器。该LCMW发生器结构简单,仅由AFL、任意波形发生器和光电探测器组成。通过将扫描信号施加到AFL的放大器部分,AFL的输出的拍频可以以啁啾的方式改变。LCMW使用外差击败技术进行了实验验证。测量的微波波形具有<inline-formula><tex-math notation="LaTeX">1 μ s</tex-math></inline-formula>的脉冲持续时间,3.3 GHz的带宽(范围从31.5到34.8 GHz),对应于<inline-formula><tex-math notation="LaTeX">3.3 × 10^{3}$</tex-math></inline-formula>的时间带宽积和<inline-formula><tex-math notation="LaTeX">2.6 × 10^{3}$</tex-math></inline-formula>的压缩比。
A linearly chirped microwave waveform (LCMW) generator based on a monolithically integrated dual-mode amplified feedback laser (AFL) is demonstrated. The proposed LCMW generator is very simple, only consisting of an AFL, an arbitrary waveform generator, and a photodetector. By applying a sweeping signal to the amplifier section of the AFL, the beating frequency of the AFL’s output can be changed in a chirped manner. LCMW is experimentally demonstrated using a heterodyne-beating technique. The measured microwave waveform has a pulse duration of <inline-formula> <tex-math notation="LaTeX">$1~\mu \text{s}$ </tex-math></inline-formula>, a bandwidth of 3.3 GHz (ranging from 31.5 to 34.8 GHz), corresponding to a time-bandwidth product of <inline-formula> <tex-math notation="LaTeX">$3.3 \times 10^{3}$ </tex-math></inline-formula> and a compression ratio of <inline-formula> <tex-math notation="LaTeX">$2.6 \times 10^{3}$ </tex-math></inline-formula>.
