摘要
本文对非线性变折射率纤维透镜进行了分析,利用高斯光束在非线性变折射率纤维中传播的稳态自聚焦理论以及在线性介质中传播的ABCD定律,导出了计算这种透镜的焦距及束腰半径的解析表达式。
The nonlinear graded index fiber lens is analysed Analyticexpressions for computing the focal length and beam waist radius ofthis lens are derived from the stationary self-focusing theory and theABCD law of Gaussian optical beam propagation.
