摘　　要：在光纤器件流变制造加热方法研究中,采用电加热方式取代传统火焰加热方式。设计一种新型熔融拉锥电加热器,并在此基础上研制了一种新型电加热式熔融拉锥机,温度控制精度和稳定性达±2℃,比气体燃烧的方式提高一个数量级。最后,在此新型电加热式熔融拉锥机上制作的光耦合器,并对其性能离散性进行分析对比。结果表明,与火焰加热式熔融拉锥机相比,电加热式熔融拉锥机成倍地提高了器件性能的一致性。Replace traditional gas-heating method by electrical heating method in optical devices manufacture, a new type of electrical FBT（Fused Biconical Taper）heater is developed. Based on this,a new type of FBT machine with electrical heater was developed which can precisely control temperature within the tolerance of ± 2℃, much better than that of gas-burning method. Lastly, fiber couplers was fabricated on this new machine and its disperse performances was compared with those made by gas-burning machine. The result shows that the new electrical FBT machine can greatly improve the conformity of the fiber devices.
