从理论上讲，不超过80%的光通过圆孔衍射可以直接耦合到普通光纤的一个模式。为了提高耦合效率，并说明一个反向的方法来设计具有所需的模式形状的光纤，我们已经做了一个光纤，引导近似艾里图案作为其模式之一。该光纤在1550 nm波长处的衰减为11.0 dB/km，光纤的模式与理想的无限艾里模式之间的匹配为93.7%，并且远场类似于礼帽光束。该引导机制与光子带隙引导具有很强的相似性。由The Optical Society根据知识共享署名4.0许可证条款发布。
In theory, no more than 80% of the light diffracted by a circular aperture can be directly coupled into one mode of an ordinary optical fiber. To improve coupling efficiency, and illustrate an inverse method for designing optical fibers with a desired mode shape, we have made an optical fiber that guides an approximate Airy pattern as one of its modes. The fiber's attenuation was 11.0 dB/km at a 1550 nm wavelength, the match between the fiber'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. Published by The Optical Society under the terms of the Creative Commons Attribution 4.0 License.
