我们在实验和数值上报道了放大反馈激光器（AFL）的直接调制带宽增强。通过制造装置，增强的？3?？dB带宽为27 GHz，带内平坦度为±3？dB在13°C下得到实验证实。数值验证了AFL的调制带宽可以提高到原来带宽的两倍，并具有更大的控制灵活性，从而实现平坦的小信号响应。
We report a direct, modulated bandwidth enhancement in a amplified feedback laser (AFL), both experimentally and numerically. By means of fabricated devices, an enhanced ?3??dB bandwidth of 27 GHz with an in-band flatness of ±3??dB is experimentally confirmed at 13?°C. It is numerically confirmed that the modulated bandwidth of the AFL can be enhanced to two times its original bandwidth, with more controlled flexibility to realize a flat, small-signal response.
