Plastic optical fibers , metal-doped

Other important hallmarks in the history of IFP include IFP systems with dopants. Ref [15] reports the first use of deuterated and fluorinated MMA derivatives to produce GRINS of lower signal loss. Additionally, Refs. [24], [25] and [50] report the use of metal-doped plastic optical fibers (POFs) to increase attenuation. In addition. Ref [26] reports the use of a two-step IFP process to...
