实现了耦合非对称微腔的单模激光输出。通过耦合两个尺寸失配的圆形微环形成耦合非对称微腔，成功地抑制了多个回音壁模，获得了稳定的单频激光发射。此外，激光器向四个方向发射，每个光束的发散度仅为6.6度。进一步证明了这种单频耦合微腔激光器可以很容易地与平面光波电路集成。我们提供了一个容易获得的方法来实现单频激光器从微腔激光器上运行的回音壁模式。(C)2008年美国光学学会。
Single-mode lasing from a coupled asymmetric microcavity is achieved. By coupling two size mismatched circular microrings to form a coupled asymmetric microcavity, multi-whispering-gallery modes are successfully suppressed and single-frequency laser emission is robustly obtained. Moreover, the laser emits in four directions, and each beam has a divergence of only 6.6 degrees. It is demonstrated further that this single-frequency coupled microcavity laser can be easily integrated with planar lightwave circuits. We provide an easily accessible approach to achieve a single-frequency laser from microcavity lasers operating on whispering-gallery modes. (C) 2008 Optical Society of America.
