我们首次从理论和实验上证明了平面光路中红外光的动态、全线性时间反转。我们建议，存储在腔中的光的振荡运动可以通过耦合腔系统的本征模的频率的快速非绝热调谐的时间反转，并实验证明它使用的系统由远距离的高Q因子的二维光子晶体腔之间形成有效的直接耦合通过线缺陷波导。我们还分析了时间反转的损耗和减小损耗的方法，并提出了一种理论，使我们的系统可以实现对任意输入光的一般时间反转操作。我们首次从理论和实验上证明了红外光在平面光路中的动态全线性时间反转。我们建议，存储在腔中的光的振荡运动可以通过耦合腔系统的本征模的频率的快速非绝热调谐的时间反转，并实验证明它使用的系统由远距离的高Q因子的二维光子晶体腔之间形成有效的直接耦合通过线缺陷波导。我们还分析了损耗和减少损耗的方法，以及扩展我们的系统以实现对任何输入光的一般时间反转操作的理论。
We theoretically and experimentally demonstrate dynamic, all-linear time-reversal of infrared light in planar optical circuits for the first time. We propose that the oscillatory motion of the light stored in cavities can be time-reversed by fast nonadiabatic tuning of the frequency of eigenmodes of a coupled cavity system and experimentally demonstrate it using a system consisting of distant high-Q-factor two-dimensional photonic crystal cavities between which effective direct couplings are formed via line-defect waveguides. We also analyze the loss and methods to reduce the loss, as well as a theory that expands our system to realize general time-reversal operation for any input light.We theoretically and experimentally demonstrate dynamic, all-linear time-reversal of infrared light in planar optical circuits for the first time.
