Ormosil coatings for POF

摘要

e of Plastic Optical Fibers' (POFs) assets, their attenuation still remains too high (usually near 200 dB.km$+$MIN@1$/ at 650 nm) and far from the theoretical one. The transmittance could be improved by optimizing the interface between the cladding and the core. Thus a process of a new ORMOSIL (ORganically MOdified SILicate) cladding which is obtained by sol-gel technology is proposed for PMMA fibers. Coupling agents are able to assure the adhesion of the core fibers by chemical links with the coating.
