我们建议使用不对称谐振微腔来有效生成比腔直径长得多的光路。该路径沿着腔内的星形多边形周期轨道形成，该轨道是稳定的并受到全内反射的限制。我们基于这个想法制造了平均直径为0.3毫米的半导体器件，并通过实验实现了2.79毫米的路径长度。
We propose using an asymmetric resonant microcavity for the efficient generation of an optical path that is much longer than the diameter of the cavity. The path is formed along a star polygonal periodic orbit within the cavity, which is stable and confined by total internal reflection. We fabricated a semiconductor device based on this idea with an average diameter of 0.3 mm and achieved a path length of 2.79 mm experimentally.
