We experimentally demonstrate and numerically analyze large arrays of whispering gallery resonators. Using fluorescent mapping, we measure the spatial distribution of the cavity ensemble’s resonances, revealing that light reaches distant resonators in various ways, including while passing through dark gaps, resonator groups, or resonator lines. Energy spatially decays exponentially in the cavities. Our practically infinite periodic array of resonators, with a quality factor (Q$Q$) exceeding 107${10}^7$, might impact a new type of photonic ensembles for nonlinear optics and lasers using our cavity continuum that is distributed, while having high-Q$Q$ resonators as unit cells.

空腔连续体

我们通过实验演示并数值分析了大型回音壁谐振器阵列。使用荧光映射，我们测量了腔体谐振的空间分布，揭示了光以各种方式到达远处的谐振器，包括穿过暗间隙、谐振器组或谐振器线。能量在空腔中呈指数空间衰减。我们的几乎无限周期的谐振器阵列，其品质因数 ( Q$Q$ ) 超过10 7${10}^7$，可能会使用我们的分布式腔体连续体，同时将高Q$Q$谐振器作为单位单元，影响非线性光学和激光器的新型光子系综。
