空芯光子晶体光纤（HC-PCFs）具有不同于传统光纤的带隙导光机制，在光通信系统、高功率激光器、工业制造和生物医疗等许多领域有广阔的应用前景。随着光纤拉制技术的不断进步，不同纤芯结构的 HC-PCFs 出现并带来了更好的光传输特性（图1）。通过设计新的纤芯形状，并运用 COMSOL Multiphysics® 中的 RF 模块进行仿真，可以研究各种纤芯 HC-PCFs 的模式（图2）、泄漏损耗（图3）和波导色散（图4）等特性。结果表明：设计的内凹圆化形纤芯 HC-PCFs 比传统的正十二边形纤芯 HC-PCFs 有更低的泄漏损耗和波导色散，而设计的内凹直线形纤芯 HC-PCFs 有很低的泄漏损耗和大的波导色散。新设计的纤芯结构未来可用于大容量光通信、光孤子传输以及色散补偿等应用中。

Auto assembled Ag-ZnO  star shaped nanostructures depicted in figure 1, presents their natural electromagnetic resonance at 60 THz. In this work we present that is possible to change this value by covering it with a variable in thickness layer of gold. The analysis is performed by numerical simulations using COMSOL Multiphysics® software.
