| 摘 要： | 设计了一种适合于中红外波段传输的GLS玻璃高双折射高非线性光子晶体光纤(PCF),利用电磁波传播的多极散射理论数值模拟了该光纤的双折射和非线性特性,并对实验制备这种软玻璃光纤的可行性进行了分析。研究发现,通过调节光纤的结构参数可以将该PCF的双折射最大值调至所需的中红外波段(3~10 m),在波长=8.214 m处模式双折射达到了0.16,且偏振方向非线性系数=0.15m-1-1,即该光纤在中红外波段同时具有高双折射和高非线性。这种光纤有望实现中红外波段超短脉冲展宽,进一步扩展中红外波段的激光源。

| Abstract: | A kind of GLS photonic crystal fiber(PCF) with high birefringence and high nonlinearity is designed in this paper.The birefringence and nonlinearity of this fiber are numerical simulated by multipole-method.And the feasibility of fabricating this PCF using theGLS glass is analyzed.It is found that thewavelength corresponding tomax birefringence can be shifted to themid-infrared band by adjusting the parameters of the PCF.For this PCF,the birefringence of is up to 0.16 and the nonlinear coefficient of-polari... |
