通过在具有微米间距的六角形气孔阵列的二维光子晶体中嵌入中心芯，我们制作了一种全硅光纤。有效折射率模型证实，这种光纤对于任何波长都可以是单模的。它在二氧化硅透明窗口内有用的单模范围虽然很宽，但最终在短波长和长波长都受到弯曲损耗边缘的限制。(C)1997年美国光学学会。
We made an all-silica optical fiber by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes. An effective-index model confirms that such a fiber can be single mode for any wavelength. Its useful single-mode range within the transparency window of silica, although wide, is ultimately bounded by a bend-loss edge at short wavelengths as well as at long wavelengths.
