光子晶体光纤的有效面积

Effective area of photonic crystal fibers

Niels Asger Mortensen

摘要:

研究了包层中含有三角形空气孔晶格的光子晶体光纤的有效面积A_eff。它首先是非线性背景下的一个重要量,但它也与泄漏损耗、宏观弯曲损耗和数值孔径有关。还可以通过比较不同模式的有效面积来研究PCF中的单模与多模操作。我们报告了大量的数值研究与不同的空气孔大小的光子晶体光纤。我们的结果可以缩放到一个给定的间距,从而提供了一个通用的地图的有效区域。我们还使用有效面积的概念来计算单模和多模操作的制度之间的“相”边界。

英文摘要:

We consider the effective area A_eff of photonic crystal fibers (PCFs) with a triangular air-hole lattice in the cladding. It is first of all an important quantity in the context of non-linearities, but it also has connections to leakage loss, macro-bending loss, and numerical aperture. Single-mode versus multi-mode operation in PCFs can also be studied by comparing effective areas of the different modes. We report extensive numerical studies of PCFs with varying air hole size. Our results can be scaled to a given pitch and thus provide a general map of the effective area. We also use the concept of effective area to calculate the "phase" boundary between the regimes with single-mode and multi-mode operation.
