前面的章节表明，玻璃中最初球形的银纳米粒子的形状可以通过飞秒激光照射永久改变；这反过来又导致复合玻璃中产生光学二色性。诱导的二色性程度（两个偏振共振之间的光谱间隙）与纳米粒子的纵横比（长轴和短轴之比）相关，取决于照射参数，例如波长、峰值强度和所施加的激光脉冲数。我们现在将探索基于金属玻璃纳米复合材料的偏振和波长选择性微型器件的制造。
It was shown in the previous sections that the shapes of the initially spherical Ag NPs in glass can be permanently modified by femtosecond laser irradiation; that in turn leads to the optical dichroism induced in the composite glass. The induced degree of dichroism (spectral gap between the two polarized resonances), being correlated with the aspect ratio (ratio of long and short axis) of the NPs, depends on the irradiation parameters such as wavelength, peak intensity and number of laser pulses applied. We will now explore the fabrication of polarization and wavelength selective micro-devices based on metal-glass nanocomposites.
