高速光内联的重要性刺激了聚合物电光器件的研究。学者们发现非线性光学聚合物的微波折射指数与光折射指数十分相近,这使得微波和光波的位相匹配成为可能。光学聚合物波导管制作技术的改进也是由于稀土才得以实现的,这是因为稀土离子有2个未填满的外壳层5s和5p,所以它可以作为很好的光放大介质,而4f内壳层亚稳跃迁辐射的波长不受基质的影响。 The importance of high speed light in-line stimulates the research of polymer electro-optic devices. Scholars found that the nonlinear refractive index of the optical polymer is very similar to that of the refractive index, which makes it possible to match the phase of the microwave with the light. Optical polymer waveguide manufacturing technology improvements are also due to rare earth can be achieved, this is because rare earth ions have two unfilled outer shell 5s and 5p, so it can be used as a good optical amplifier medium, and 4f inner shell Layer metastable radiation wavelength is not affected by the matrix.
