Optical waveguides of plastic usually consist of a core and a jacket, the core material having a higher refractive index than the jacket material. A suitable core material is a fluorine-free polymer and a suitable jacket material is a fluorine-containing polymer, which can also contain deuterium. The optical waveguides can be produced by passing a polymer rod through a solution of the jacket polymer and then removing the solvent. The optical waveguides are particularly suitable for the transmission of data with the aid of light waves with a wavelength of 500 to 750 nm.
塑料光波导通常由芯和护套组成,芯材料的折射率比护套材料高。适用的芯材料是不含
氟的聚合物,适用的护套材料是含
氟聚合物,也可以含有
氘。光波导可以通过将聚合物棒通过护套聚合物溶液并去除溶剂来制造。光波导特别适用于利用波长为500至750纳米的光波传输数据。
