非线性梯度折射率棒透镜高斯光束的色差

Derivation for the coupling coefficient and power loss of a demountable connector with graded index fibers is made in this paper by means of Wigner distribution function in the phase space. Numerical results are calculated by the computer.

本文介绍用相空间中的Wigner分布函数，推导渐变折射率活动连接器中两光纤有一间隙时的耦合系数和功率损失，并算出了数值结果。

The method can be applied to the functions with two free coefficients, such as the Fermi function, so that it can be used to recover the graded index profiles with wide variation range.

该方法把统计优化手段导入循环迭代法，可适用于费米函数这一类曲线变化范围大、且有多个自变量的函数。
