摘　　要：针对传统塑料光纤在传输过程中损耗大,使用长度较短的问题,提出在光纤连接部位制备一种新型共轭聚合物CN-PPV掺杂塑料光纤放大器材料,并对其制备工艺、荧光特性和增益特性进行研究。试验结果表明,在25 mL MMA、0.032 g BPO、20~75μL n-BM的工艺条件下制备的预制棒表面状态良好,内部无气泡出现,并在拉伸温度为150~177℃的条件下成功拉丝。塑料光纤最大发射截面为1.7×10^(-20) m^(2);当泵浦光传输距离增加,光谱出现明显红移现象,最大红移波长为12 nm。在光纤长度为50 cm的条件下,掺杂质量浓度为1 mg/L的光纤存在最大增益值,达到25 dB。而掺杂质量浓度为0.2 mg/L的光纤具备持续光放大能力,更适合作为光纤放大器的制备材料。Aiming at the problems of large loss and short service length of traditional plastic optical fiber in the transmission process,a novel conjugated polymer CN-PPV doped plastic optical fiber amplifier material was proposed at the fiber connection part,and its preparation process,fluorescence characteristics and gain characteristics were studied.The test results showed that the preform prepared under the technological conditions of 25 mL MMA,0.032 g BPO,20~75μL n-BM had a good surface condition without bubbles inside,and the wire was successfully drawn at the stretching temperature of 150~177℃.The maximum emission cross section of plastic optical fiber was 1.7×10^(-20) m^(2).When the transmission distance of the pump light increased,the spectrum showed obvious red shift,and the maximum red shift wavelength was 12 nm.When the fiber length was 50 cm,the fiber with doping concentration of 1 mg/L had a maximum gain value of 25 dB.The fiber doped with 0.2 mg/L concentration had the ability of continuous optical amplification,which was more suitable for the preparation material of optical fiber amplifier.
