摘要阐述了三维波导结构的FD-BPM原理,并用FD-BPM法模拟了波长为1.54μm和0.98μm的高斯光束在Er3+-Yb3+共掺磷酸盐玻璃光波导内光场分布.与沟道光波导相比,掩埋型光波导内的泵浦光和信号光的散射都非常小,光场分布非常均匀.研究结果表明,掩埋型光波导是制作Er3+-Yb3+共掺磷酸盐玻璃光波导激光器和放大器的理想波导. We introduce FD-BPM to three-dimensional waveguides and calculate the refractive index of Er^3＋＋ -Yb^3＋ co-doped phosphate glass waveguides. The simulation for a signal light（ 1.54μm）and a pump light（0.98μm） is performed in a Er^3＋ -Yb^3 ＋ co-doped phosphate glass waveguide with FD-BPM. It shows that the scatter loss can be neglected and the optical field is symmetric in a buried waveguide. A buried Er^3＋ -Yb^3＋ co-doped phosphate glass waveguide is demonostrated the best to make Er^3＋ -Yb^3＋ co-doped phosphate glass waveguide lasers and amplifiers.
