We investigate photonic transport through fiber optical cavities under tunable fast modulation, which is induced by modulating atom-cavity coupling in a cavity quantum electrodynamics (CQED) system. The modulation bandwidth exceeds the timescales of all other system processes, such as cavity decay and atom-cavity coupling, and allows control of the dynamics of photonic transport through the cavity array. The transmission as a function of the modulation frequency clearly shows enhancement peaks in single cavity and two coupled-cavity cases. In particular, in the coupled-cavity case, the position of the enhancement peak is shifted due to the delocalized cavity field in the coupled system.
我们研究了在可调谐快速调制下通过光纤光学腔的光子传输，这种调制是由腔量子电动力学（CQED）系统中调制原子 - 腔耦合引起的。调制带宽超过了所有其他系统过程的时间尺度，如腔衰减和原子 - 腔耦合，并允许控制通过腔阵列的光子传输动力学。作为调制频率函数的传输在单腔和双耦合腔情况下清楚地显示出增强峰。特别是，在耦合腔情况下，由于耦合系统中腔场的离域化，增强峰的位置发生了移动。
