摘　　要：采用时域有限差分法对D形光纤进行分析,研究D形光纤包层切除深度、切除长度、涂层折射率和背景折射率对光纤中传输能量的影响。计算结果表明,改变结构参数可以控制光纤中传输能量的变化。The current study employed the finite difference time domain method to analyze D-shaped optical fiber. Major parameters tested included the cladding removal depth,the cladding removal length,the refractive index of coating and the refractive index of background on the influence of energy in the optical fiber. The results showed that changing the structure of the D-shaped optical fiber could control the energy in the fiber.
