实验研究了熔烧温度对双锥光纤光学特性的影响。结果表明，熔烧温度影响输出功率随拉伸长度振荡的曲线形状及调制度。为获得一定的透过谱周期，所需的振荡次数随熔烧温度的升高而减小 The influence of sintering temperature on the optical properties of biconical fiber was experimentally studied. The results show that the melting temperature affects the curve shape and modulation of the output power oscillating with the stretching length. In order to obtain a certain pass spectral period, the number of oscillations required decreases with increasing sintering temperature
