中文摘要：
以多极法理论为基础,设计了一种混合双包层结构的光子晶体光纤.通过改变其五层空气孔的四个结构参数（内层空气孔直径、外层空气孔直径、六边形孔间距和八边形孔间距）,理论上实现了色散绝对值在1.44—2.0μm的波段内变化仅为1.25ps·km-1·nm-1的平坦色散特性.在此情况下对其损耗进行了数值模拟,使所设计的光纤在1.44—2.0μm的宽波段范围内具有小于0.005dB/km的低限制损耗特性.
英文摘要：
Based on multi-pole method theory,a kind of hybrid cladding photonic crystal fiber（PCF） is designed.It has been shown theoretically that it is possible to obtain fiattened dispersion charactor of dispersion absolute value 1.25 ps·km-1· nm-1 within the wave band of 1.44 μm to 2.0 μm by altering four structure parameters of the five-ring hybrid cladding in the PCF（namely the diameter of the inner ring hole,the diameter of the outer four ring holes,the pitch of the hexagon and the pitch of the octagon）.Moreover,value simulation results show that in the PCF low confinement loss of 0.005 dB/km in the 1.44—2.0 μm wavelength range can be achieved.
