摘　　要：目前商用化光纤光栅温度传感器仍然存在易受应力影响,光纤荧光和砷化镓温度传感器无法与光纤通讯系统集成等缺陷。为了解决这一问题,提出一种通讯用单模光纤跳线陶瓷插芯端面上负载聚丙烯酰胺(Polyacrylamide,PAM)薄膜的温度传感器,通过探寻温度与薄膜干涉光谱谐振谷波长之间的关系,实现了温度的实时检测。结果表明,在48℃~64℃的温度范围内,PAM溶液浓度为1%时,灵敏度为58.47 pm/℃.该传感器以通讯波段作为响应波长,可与光纤通讯系统直接集成,成本低,应力免疫,可用于各类设备的温度监测场景。Commercial fiber grating temperature sensors are vulnerable to stress and have deficiencies.Meanwhile,fiber fluorescence and gallium arsenide temperature sensors cannot be integrated into fiber communication systems.To address these problems,a temperature sensor integrating a polyacrylamide(PAM)film on the end face of the ceramic ferrule of the communication single-mode fiber jumper is proposed.By exploring the relationship between temperature and the wavelength of the resonant valley in the film's interference spectrum,real-time temperature detection is realized.The results show that within the temperature range of 48-64℃,when the concentration of the PAM solution is 1%,the sensor has the sensitivity of 58.47 pm/℃.This sensor,which takes the communication band as the response wavelength,can be directly integrated into the fiber communication system.It is low-cost and stress-resistant,and thus applicable to the temperature monitoring of various equipment.
