利用非侵入式脉冲跟踪技术观察了超短光脉冲在集成光学微谐振腔中的时间分辨运动。我们跟踪一个脉冲，因为它在谐振器中完成了几次往返，直接映射了空间和时间中的谐振器模式。我们的时间依赖性和相敏测量提供了直接访问的谐振器中的模式的角群和相速度。从测量的接入波导和谐振器之间的耦合常数检索，而在同一时间的整个结构的损耗机制直接可视化。
A noninvasive pulse-tracking technique has been exploited to observe the time-resolved motion of an ultrashort light pulse within an integrated optical microresonator. We follow a pulse as it completes several round trips in the resonator, directly mapping the resonator modes in space and time. Our time-dependent and phase-sensitive measurement provides direct access to the angular group and phase velocity of the modes in the resonator. From the measurement the coupling constants between the access waveguides and the resonator are retrieved while at the same time the loss mechanisms throughout the structure are directly visualized.
