Based on experimental results obtained for various types of glass, it was found that the tendency in the elemental distribution depended on the strength of the bond. The temperature gradient should be responsible for element migration, i.e., this phenomenon should be interpreted as thermomigration. In the case of the phosphate glass, it was also confirmed that Ge and Ga were moved to the center in the laser irradiated area. With this phenomenon, an optical waveguide was formed and we succeeded in guiding light through it. Additionally, space-selective crystallization of nonlinear optical crystal inside glass was achieved. It was also confirmed that various shapes of element distribution can be produced by making multiple irradiated points with a LCOS-SLM. The spatial distribution of glass components is very important for controlling the property of glass, because the composition of a glass affects its chemical, mechanical and optical properties.

根据不同类型玻璃的实验结果，发现元素分布的趋势取决于键的强度。温度梯度应负责元素迁移，即，这种现象应被解释为热迁移。在磷酸盐玻璃的情况下，也证实了Ge和Ga在激光照射区域向中心移动。利用这种现象，形成了一个光波导，我们成功地引导光通过它。此外，还实现了非线性光学晶体在玻璃内部的空间选择性结晶。用LCOS-SLM制作多个辐照点可以产生不同形状的元素分布。玻璃组分的空间分布对于控制玻璃的性能是非常重要的，因为玻璃的组成影响其化学、机械和光学性能。
