Abstract

An optical polymer fibre doped by neodymium octoate is prepared through reaction between neodymium carbonate, methanol and octanoic acid at 60 + / - 20 deg.C, educing neodymium octoate crystal, prepolymerization between neodymium octoate crystal, azodiisobutyl cyanogen and n-butyl thiol at 75-95 deg.C while stirring, solidifying at 40-65 deg.C to obtain prefabricated rod, drawing, and coating low-refractivity resin layer. Its advantages are high compatibility of rare-earth ions and optical stability and big diameter (300-1500 microns).

Description

Technical field: [0001] The invention relates to the technical field of neodymium-doped polymer optical fiber and its preparation method. Background technique: [0002] Today, with the increasing amount of information transmission, traditional cables can no longer meet people's needs, while optical fiber has become one of the important transmission media of communication systems due to its advantages of low loss and large capacity. China's "Optical Fiber Communication and Network Technology" (published by Beijing University of Aeronautics and Astronautics Press in October 1999, Chapter 1) pointed out that due to its small core diameter, the traditional inorganic optical fiber has complicated cutting and connecting operation techniques, branching and coupling. Disadvantages such as trouble, the application of optical fiber to the home is limited; the optical communication window of inorganic glass optical fiber is 1.3um and 1.5um, which limits its application in some occasion...
