本文提出了一种大有效模场面积微结构光纤的数值设计方法。利用时域有限差分数值模拟方法，结果表明，该光纤具有12 2 ~ 2 5 2 μ m2量级的有效面积，在15 5 0 nm波长附近具有负色散平坦特性，以及10 - 5dB/km量级的低限制损耗。使用具有两个空气孔尺寸和共同间距的六边形八环二氧化硅-空气微结构。具有大有效模面积、低限制损耗和色散平坦特性的微结构光纤有望用于下一代光数据传输。
This paper presents a numerical design of a large effective mode area microstructure optical fiber. Using the finite difference time domain numerical simulation method it is shown that the proposed fiber can assume very high effective area of the order 122 to 252 μm 2 , negative dispersion-flat properties around the 1550 nm wavelength, and very low confinement losses of the order 10 –5 dB/km. A hexagonal eight ring silica-air microstructure is used with two air-hole dimensions and a common pitch. A microstructure optical fiber with large effective mode area, low confinement loss, and dispersion-flat property may be promising for next generation optical data transmission applications.
