我们设计并制作了一种光导纤维，它的导模之一是近似的艾里斑图。在1550 nm波长处，光纤的衰减为11.0 dB/km，光纤的模式与理想的无限远艾里模式的匹配率为93.7%，远场近似于礼帽光束。该引导机制与光子带隙引导具有很强的相似性。
We have designed and made an optical fibre that guides an approximate Airy pattern as one of its guided modes. The fibre's attenuation was 11.0 dB/km at 1550 nm wavelength, the match between the fibre's mode and the ideal infinite Airy pattern was 93.7%, and the far field resembled a top-hat beam. The guidance mechanism has strong similarities to photonic bandgap guidance.
