我们已经成功地制造出光子寿命为2.1 ns的光子晶体纳米腔，其对应于2.5 × 10（6）的品质因子。这是迄今为止光子晶体腔中记录的最长寿命，并且是由制造工艺的改进带来的。比较我们的实验品质因数与计算结果表明，我们已经抑制了组成纳米腔的空气孔的半径和位置的变化，使得它们的标准偏差小于1 nm。
We have succeeded in fabricating a photonic crystal nanocavity with a photon lifetime of 2.1 ns, which corresponds to a quality factor of 2.5 x 10(6). This lifetime is the longest recorded thus far in photonic crystal cavities, and was brought about by improvements in the fabrication process. Comparing our experimental quality factor with the results of calculations shows that we have suppressed variations in the radii and positions of the air holes composing a nanocavity such that their standard deviations are less than 1 nm.
