摘　　要：主要分析带隙型全固双芯光子晶体光纤填充高温度系数折射率敏感介质后的温度特性。应用平面波展开法和全矢量有限元法研究温度对其模场分布、有效折射率、耦合长度及温度传感的影响。理论计算结果表明,耦合长度随温度升高出现单极值或多极值点,奇模式的有效折射率随着温度的变化或波长的变化会出现跳变情况。We analyze the temperature characteristics in all-solid dual-core photonic bandgap fibers, which is filled with the refractive index sensitive to high temperature. We use plane wave expansion method and full vector finite element method effective refractive index, cou that, the supermode to analyze the effect of temperature on their mode field distribution, the pling length and the sensitivity. Theoretical calculations and results show coupling length occurs one or more extreme points with increasing temperature, and odd effective index changes greatly with temperature or the wavelength.
