Method for synthesizing ultraviolet-writable fluorine-containing erbium-containing polymer waveguide amplifier material

Abstract

The invention relates to a method for synthesizing an ultraviolet-writable fluorine-containing erbium-containing polymer waveguide amplifier material and belongs to the field of synthesis of polymer near-infrared light-emitting materials. According to the method, a fluorine-containing active monomer containing an olefin double bond and an epoxy group, an erbium-containing complex and epoxypropyl methacrylate are subjected to ternary polymerization to prepare a fluorine-containing erbium-containing polymer near-infrared light-emitting material so that the compounding of an erbium ion and the polymer at the molecular level is achieved and the fluorescence quenching caused by uneven concentration of a rare earth complex due to phase separation generated by uneven doping is avoided. Polymer optical waveguide amplifier micro-patterns with stripe structures are prepared by carrying out lithography development on a polymer film obtained by a spin coating through a direct ultraviolet-writing technology, compared with the traditional process, copying processes such as evaporating a metal film layer and ion etching are not needed and thus the process steps are reduced and meanwhile, the cost is decreased and the method is an advantageous method for producing a polymer waveguide amplifier.
