| 摘 要： | 利用多极法分析了PCF的色散补偿特性,找到了色散随结构参数的变化规律.根据此规律,设计了W型色散补偿PCF.该PCF l550nm处色散值为-402.7ps·km-1·nm-1和色散斜率为-1.427ps·km-1·nm-2.利用Opti Sim平台仿真出基于色散补偿PCF的DWDM系统,结果表明,系统中的误码率均小于10-22,达到了通信的要求.

| Abstract: | By using multipole method,the paper analyse the dispersion-compensating compentsate properties of PCF and the variety rule of dispersion with structure parameter.Based on those variety rule,we design W type of dispersion-compensating PCF,which is nine rings of air hole.Its dipersion and dispersion slope are-402.7ps.km-1.nm-1 and-1.427ps.km-1.nm-2 at 1550nm.we design DWDM system based on dispersion-com-pensating pcf using the soft of Optisim.The result shows that the error code rate is littler than 10-12,whi... |
