电磁感应透明在许多物理学领域，如原子物理学、量子光学和最近的腔光学力学中具有重要的理论和实验意义。光延迟是电磁感应透明最显著的特征，而在腔光力学中，光延迟受到边带分辨机械模的机械耗散率的限制。在这里，我们演示了一个级联的光学透明方案，通过利用参量声子-声子耦合在多模光学机械系统，其中低阻尼机械模式在未分辨边带制度耦合到一个中间，高频机械模式在光学腔的分辨边带制度。扩展的光延迟和更高的传输以及光学进步的表现。这些结果为实现超长光延迟提供了一条途径，标志着向集成经典和量子信息存储器件迈出了重要一步。
Electromagnetically induced transparency has great theoretical and experimental importance in many areas of physics, such as atomic physics, quantum optics and, more recent, cavity optomechanics. Optical delay is the most prominent feature of electromagnetically induced transparency, and in cavity optomechanics, the optical delay is limited by the mechanical dissipation rate of sideband-resolved mechanical modes. Here we demonstrate a cascaded optical transparency scheme by leveraging the parametric phonon-phonon coupling in a multimode optomechanical system, where a low damping mechanical mode in the unresolved-sideband regime is made to couple to an intermediate, high-frequency mechanical mode in the resolved-sideband regime of an optical cavity. Extended optical delay and higher transmission as well as optical advancing are demonstrated. These results provide a route to realize ultra-long optical delay, indicating a significant step towards integrated classical and quantum information storage devices.
