碩士 === 義守大學 === 電機工程學系 === 101 === Through Vector Boundary Element Method, this thesis is analyzing and simulating elliptical-hole photonic crystal fiber. For the propagation modes, we change the air hole radius, elliptical ratio, wavelength, and turn the angle of air hole structure. In here, we analyze not only in the characteristics of mode also including polarization. As shown in the result, we will discuss the effective index of the EPCF, we knows inversely proportional to relationship of effective index and wavelength. At η=1.2, the effective index is the maximum value. Therefore, we will discuss the polarization of the EPCFs, the relationship between the birefringence and the wavelength is direct ration. By analyzing turn the angle of air hole’s 90-degrees-polarization, it’s found that the birefringence is clearly more obvious than its original structure. The highest birefringence rate is 0.0008.
