摘要
设计了一种双芯光子晶体光纤(PCF),并在其两个纤芯中填充混合热敏液体,采用全矢量有限元法和光纤模式耦合理论,研究了温度对填充后PCF的有效折射率、双折射、耦合长度以及限制损耗的影响。研究表明,参量对温度比较敏感,且PCF双折射达到10-3数量级。
Design a dual core PCF and fill with mixed thermal liquid in its two core. With the full vector finite element method and the fiber mode coupling theory, temperature has effects with the effective refractive index, birefringence, the coupling length and the confinement loss of the filled PCF. Research shows that these parameters are more sensitive to the temperature. With the design of the fiber birefringence in the level of 10^-3.
