本文报道了用飞秒激光直接写入技术（FsLDW）制备染料掺杂聚合物光子分子（PM）微激光器，并通过改变微腔中两个圆盘之间的距离来研究其激光行为。研究发现，当两个圆盘的距离变小时，两个圆盘之间发生耦合，导致激光模式减少。但是，当两个圆盘交叉时，低语通道模腔的圆形对称被打破，增加了激光阈值。利用FsLDW的三维制造能力，我们的研究结果为研究用于光子器件集成的复杂三维耦合微腔开辟了可能性。
We report on fabrication of dye-doped polymer photonic-molecule (PM) microlasers by femtosecond laser direct writing (FsLDW) and investigate their lasing behaviors by changing the distance between the two disks in the microcavities. It is found that when the distance of two disks becomes smaller, the coupling between two disks occurs, leading to a decrease of the lasing modes. But, when two disks are crossed, the circular symmetric of whispering-gallery mode cavities are broken, increasing the lasing thresholds. With the three-dimensional (3D) fabrication capacity of FsLDW, our result opens up a possibility of investigating complex 3D coupled microcavities for photonic device integration.
