论文摘要
我们在自由空间设置中以两种光学反馈进行实验研究的半导体激光器。我们表明，与单个反馈的激光器相比，在混乱的输出强度中表现出来的时间延迟签名可以更好地抑制。我们证明，反馈阶段的控制对于抑制时间延迟签名至关重要，与一案例相比，反馈阶段也影响了反馈阶段，也影响了混乱的带宽。通过优化反馈阶段，时间延迟签名可以减少2倍，同时保持较大的混乱带宽。
We experimentally study a semiconductor laser subject to two optical feedbacks in a free space setup. We show that the time delay signature, manifesting itself in the chaotic output intensity, can be better suppressed than in a laser with single feedback. We demonstrate that the control of the feedback phase is essential to suppress the time delay signature, in contrast to the one-delay case, and that the feedback phase also impacts the chaotic bandwidth. By optimizing the feedback phase the time delay signature can be reduced by a factor of 2 while maintaining a large chaotic bandwidth.
