用FD-BPM模拟不同折射率下光纤的光场分布
Optical Field Distribution in Optical Fiber with Different Refractive Index Distributions by FD-BPM
【摘要】 利用有限差分光束传播法(FD-BPM)模拟出在不同折射率下的均匀光纤、锥形光纤及光纤对接中的光场分布,着重分析光纤的不同折射率分布对光纤传输能量以及光纤传输中造成能量损耗的影响,为研究不同折射率下光纤的能量传输特性奠定了理论基础.
【Abstract】 The optical field distribution in optical fiber, tapered optical fiber and optical fiber connecting with different refractive index distributionsis simulated by FD-BPM. The influence of energy transmissionand energyloss in the optical fiber with different refractive index distributions is analyzed, which is the foundation of studying the energy transmission characteristic.
