摘要
提出了一种新型双包层结构的微结构光纤(MOF),利用有限元法对其模场面积、损耗及色散系数随波长的变化规律进行了数值模拟与分析,并在相同条件下与传统的双包层MOF作了比较。结果表明,该种光纤不但结构新颖,而且较传统光纤有更优异的色散性能。通过合理优化,设计了几种在500nm波长范围内保持低平色散和较大模场面积的新型双包层MOF。这种光纤结构的提出对以后的理论研究和工艺制备具有一定的参考意义。
Using the finite element method （FEM）, the mode area, confinement loss and dispersion property of a novel microstructured optical fiber （MOF） with double-cladding structure are numerically simulated, analyzed and compared with those of traditional MOF. Results show that the fiber not only has a novel structure but also has better dispersion performance than the traditional photonic crystal fiber. Through rational optimization, several flat dispersion MOFs with large mode area in the 500 nm wavelength range are designed. The novel fiber proposed will have some reference value to the subsequent theoretical study and manufacture.
