理想的一维和理想的径向梯度折射率分布所需的浓度依赖性扩散系数的确定。修正的准化学扩散模型被用来与扩散系数的最佳玻璃组成。向硅酸钠玻璃中添加铝有助于接近银-钠离子交换的扩散系数的所需浓度依赖性。在其中一个玻璃中制造抛物线一维折射率分布。它偏离理想值小于2%。(C)1996年美国光学学会
The required concentration-dependent diffusion coefficients for both ideal one-dimensional and ideal radial gradient-index profiles are determined. The modified quasi-chemical diffusion model is used to relate the diffusion coefficient to optimum glass composition. Adding aluminum to sodium silicate glasses facilitates the approach to the desired concentration dependence of the diffusion coefficient for silver-sodium ion exchange. A parabolic one-dimensional index profile is fabricated in one of the glasses. It deviates from ideal values by less than 2%. (C) 1996 Optical Society of America
