Thermal analysis of fused biconical taper in the process of optical fibre coupler pre-drawing

光纤耦合器预拉时熔 锥区的 热分析

Based on thermal rheological theory and time-temperature equivalent principle the generalized Maxwell model was used to simulate viscoelastic characteristic of fused optical fiber glass . The thermal viscoelastic model of fiber coupler in the process of fused biconical taper was set up .

根据热粘弹流变理论和时温等效原理，以广义Maxwell模型模拟高温下熔融光纤玻璃的粘弹特性，建立了光纤耦合器熔融拉 锥过程 热粘弹数值分析模型；
