实验上阐明了六角形GaN微盘中准回音廊模式(QWGM)产生的激光的周期辐射模式和循环方向。来自微盘的辐射激光是高度定向的，所获得的辐射激光的高强度在平面方向上具有120°的周期间隔。结果表明，QWGM产生的激光在微盘中沿单一方向循环，即顺时针或逆时针。
We have experimentally elucidated the periodic radiation patterns and circulating direction of the lasing light generated by the quasi-whispering-gallery mode (QWGM) in a hexagonal GaN microdisk. The radiated lasing light from the microdisk is highly directional, with the high intensities of the obtained radiated lasing light having a periodic spacing of 120° in the planar direction. The results show that the QWGM-generated lasing light circulates in a single direction in the microdisk, namely, either clockwise or counter-clockwise.
