我们提出了一种由相干反馈引起的光透明效应。通过研究由线性相干反馈控制的线性光腔组成的系统，我们证明了通过系统腔的光信号场具有新颖的透明行为。系统与其反馈控制回路之间的单向耦合使得能够分别调谐群速度和传输速率，从而在群速度被显著抑制时保持单位传输速率。此外，我们证明了简单地施加一定的相移到系统腔的输出，并将其反馈到系统可以诱导完美的传输。我们的建议提供了一个简单而有效的方法来控制光的传输和群速度只使用线性光学元件。(C)根据OSA开放获取出版协议的条款，2020年美国光学学会
We propose a light transparency effect induced by coherent feedback. By studying a system comprising a linear optical cavity controlled by a linear coherent feedback loop, we show that the optical signal field passing through the system cavity exhibits novel transparency behaviors. Unidirectional coupling between the system and its feedback control loop enables the group velocity and transmission rate to be tuned separately, thus maintaining the unity transmission rate when the group velocity is significantly suppressed. Furthermore, we demonstrate that simply applying a certain phase shift to the output of the system cavity and feeding it back into the system can induce perfect transmission. Our proposal offers a simple and effective way to control light transmission and group velocity using only linear optics elements.
