空心光子晶体光纤(PCF)的空气填充率是影响PCF性能的一个重要参数。针对几种不同的空气填充率,设计出了几种不同结构的空心PCF。应用平面波展开法对其进行了研究,分析讨论了空气填充率对特殊结构PCF泄漏模以及色散系数的影响。 相似文献

Investigation on bismuth-oxide photonic crystal fiber for optical parametric amplification 总被引:1,自引:0,他引:1
A hexagonal solid-core bismuth-oxide micro-structure fiber is developed to balance its dispersion and nonlinearity.This simulation and calculation results show that the bismuth-oxide photonic crystal fiber(Bi-PCF) has near zero dispersion around 1550 nm.Its dispersion slop in the communication wavelength range is also relatively flat.Moreover,both nonlinear coefficient and model field distribution are obtained.Compared with the experimental results by SiO2-PCF,it can be seen that the Bi-PCF shows excellent characteristics for the optical parametric amplification(OPA). 相似文献
