Photon crystal fibre in 1992 by ST.J.Russell and others. Ordinary singlemode fiber with different PCF is ranked by the cyclical single quartz materials constitute air Kong, also known as porous fibre (holey fiber), or micro-fibre structure (micro-structured fiber). Since PCF air Kong ranked the size of a large control room and can be designed according to the PCF optical transmission characteristics, it has stimulated interest. This is seize this hot, using software to photon beamprop crystal fibre transmission characteristics of a simulation, by changing the optical spacing Kong, Zhankongbi parameters to observe changes in the national market. On the basis of a specific design oval double cladding structure, through its transmission characteristics beamprop simulation software.
