是由其中周期性排列空气孔的单一石英材料构成，所以又被称为多孔光纤（holey
fiber）或微结构光纤（micro-structured fiber）。由于PCF的空气孔的排列和大小有
很大的控制余地，可以根据需要设计PCF的光传输特性，所以它得到了人们很大的关注。
本文就是追踪这一热点，利用Beamprop软件对光子晶体光纤的传输特性进行模拟，通过
改变光纤的孔间距、占空比等参数来研究模场的变化。在此基础上具体设计了一个椭圆
双包层结构，通过Beamprop软件模拟其传输特性。
Photonic crystal fiber is brought in by ST.J.Russell on 1992. Be different
from the ordinary fiber, PCF is constituted with simplex quartz material
which contains periodic air holes. So it is also called as holey fiber or
micro-structured fiber. We can design the size and arrangement of air holes
to change the property of transmission we need, so PCF got great attention.
Concentrated on this research upsurge, this paper simulate the transmission
property of PCF and research the variation of the transverse mode through
changing parameters such as period and size of air holes. Based on above we
design a ellipse structure and simulate its mode with Beamprop software.
1)on 1992 -> in 1992
2)第三句owing that the arrangement and size of the air holes are controllable,people can design the transmission property accoring to requirements.
2)倒数第二句，simulate的主语应该不是this paper. The paper is concentrate on this research upsurge,using Beamprop to simulate the transmission property of PCF and through adjusting parameters such as period and size of air holes to study the changes of the transverse mode.
3)a ellipse-> an ellipse
Photon crystal fibre in 1992 by ST.J.Russell and others. Ordinary singlemode fiber with different photon crystal fibre By the cyclical configuration of a single quartz materials constitute air Kong, also known as porous fibre (holey Fiber), or micro-fibre structure (micro-structured fiber). PCF Kong because of the configuration and size of the air with Great control room, according to the needs of optical transmission characteristics PCF design, it was one big concern. This is the hot track, the use of photon Beamprop software simulation crystal fibre transmission characteristics, through The change fibre Kong intervals, Zhankongbi parameters to study modules market changes. On the basis of a specific design oval Double-cladding structure, through its transmission characteristics Beamprop simulation software.
