摘要


本文採用有限元素法分析高雙折射與低損耗之數值模型導模光子晶體光纖,並且與其它結構相比。數值模型採用一個包層的橢圓形空氣孔與修改的核心和實心二氧化矽(SiO2)包層兩個半大小的空氣孔。模擬結果證實,此結構在入射波長λ=1550nm處有極高的雙折射差(2.085×10-2)和超低限制損耗(1.63×10-5dB/km)。本文針並對這種設計的優點,通過減少空氣孔或者其中兩個靠近纖蕊的方式,作一有系統的探討與研究。

並列摘要


A high birefringence and low loss of index-guiding photonic crystal fiber (PCF) is proposed and compared to other structures using the finite element method. The proposed structure is composed of a cladding with modifying elliptical air holes and a core of solid silica surrounded with two half-size air holes. Numerical results confirm that the proposed structure at the excitation wavelength of λ= 1550 nm provides extremely high birefringence (~2.085×10-2) and ultralow confinement loss (<1.63×10-5dB/km). The merit of the designed PCFs is that the high birefringence and low confinement loss can be easily achieved by reducing two air holes which are near the fiber core.
