光纤的色散管理与控制是设计光电子器件中必须考虑的重要因素。光子晶体光纤(PCF)作为一种新颖的光传输介质，由于其自由的结构设计，使它在色散控制与管理方面优于常规的通信光纤，因此在很多方面有巨大的应用前景。介绍了改变PCF的几何结构对其色散的控制以及实现平坦色散的实例，着重回顾了近年来PCF在色散平坦方面的结构设计，总结了色散平坦PCF在实际中的一些应用情况。

The management and engineering of optical fiber is a necessary factor to be considered in the design of photoelectronic device. As a new kind of light transmission media, photonic crystal fiber (PCF) has an enormous application potential in many fields on account of its large configuration design freedom which makes its performance in the management and engineering of dispersion much more better than that of the conventional communication fibers. Firstly the management of dispersion by changing the geometric structure of PCF and the achievement of flattened dispersion is discussed. After that，the configuration designs of these years to realize flattened dispersion in PCF are emphatically presented, and the applications of its flattened dispersion is also summarized.
