Suspended-core fibers (SCFs) with a submicron diameter hole in the core offer interesting new possibilities in dispersion management, light confinement, and nonlinear applications. We discuss the geometric demands and options of fused silica-based nanohole SCFs suitable for all-normal dispersion (ANDi) and compare them to the possibilities provided by photonic crystal fibers (PCFs). We show that nanohole SCFs extend the options PCFs provide, enabling ANDi further into the near infrared. In addition, fabrication conditions are evaluated, a reliable fabrication scheme is outlined, and ANDi nanohole SCFs are demonstrated.

全普通色散纳米孔悬浮芯纤维的设计与制造

在纤芯中具有亚微米直径孔的悬浮纤芯纤维（SCF）在色散管理，光限制和非线性应用中提供了有趣的新可能性。我们讨论了适用于全正态色散（ANDi）的熔融石英基纳米孔SCF的几何要求和选择，并将它们与光子晶体光纤（PCF）提供的可能性进行了比较。我们表明，纳米孔SCF扩展了PCF提供的选项，从而使ANDi进一步进入了近红外领域。此外，评估了制造条件，概述了可靠的制造方案，并演示了ANDi纳米孔SCF。
