摘要
全内反射型光子晶体光纤纤具有为高折射率,包层为石英-空气周期结构,光通过高折射率纤芯与低平均折射率包层间的全内反射向前传播.包层的周期结构要求也不严格,甚至可以无序.利用其特有的"无截止单模"特性,对大模场光子晶体光纤进行了设计.
Total internal reflection PCF core has high refractive index,and the cladding is quartz-air periodic structure. The light travels forward through high refractive index core and total internal reflection among claddings with lower average refractive index. The requirement for periodic structure of cladding is not strict,even disordered. Using its ＂endless single mode＇characteristic, the PCF of large mode field has been designed.
