逆抛物型梯度折射率纤维的光传播理论

Theory of Light beam Propagation Through a Reversal Parabolic Gradient Index Fiber

本文从光线方程和近轴波动方程出发,研究了光在逆抛物型梯度折射率纤维中的传播规律。详细分析了纤维特性参数(g_0、L)及入射光束参数(ω_0)对光传播特性的影响,得出了对开拓梯度折射率纤维透镜在激光光电子装置中应用的有益的结论。

Starting from the ray equation and paraxial wave equation, the light beampropagation through a reversal parabolic gradient index fibers is studied. Theeffects of the fiber characteristic parameters (g_0, L) and the incident light beamparameter ω_0 on the light beam propagation characteristics are analysed in detail.Results are obtained, which are useful for the application of gradient in dex fiberlens in the opto-electronic and laser devices.
