Hollow-core photonic crystal fibres have excited interest as potential ultra-low loss telecommunications fibres because light propagates mainly in air instead of solid glass. We propose that the ultimate limit to the attenuation of such fibres is determined by surface roughness due to frozenin capillary waves. This is confirmed by measurements of the surface roughness in a HC-PCF, the angular distribution of the power scattered out of the core, and the wavelength dependence of the minimum loss of fibres drawn to different scales.
空心光子晶体光纤作为潜在的超低损耗电信光纤引起了人们的兴趣，因为光主要在空气中而不是固体玻璃中传播。我们提出，这种光纤衰减的最终极限是由因冻结的毛细波导致的表面粗糙度决定的。对空心光子晶体光纤表面粗糙度的测量、从纤芯散射出的光功率的角分布以及拉制成不同尺寸的光纤最小损耗的波长依赖性的测量证实了这一点。
