    • 摘要: 采用三能级系统的速率方程和功率传输方程并考虑温度对各项参数的影响,求解在不同的光纤长度和量子点掺杂浓度时,3.3 nm PbSe量子点液芯光纤的发射光谱随温度的变化.发现当光纤长度不同时,随着温度的升高,光谱的峰值位置以相近的速率发生红移,光谱的峰值强度下降.对于较长的光纤,其光强随温度升高的衰减速率较大.当掺杂浓度不同时,随着温度的升高,光谱的峰值位置以相近的速率发生红移,峰值强度以相近的速率衰减.%Three-level system-based rate equation and power transfer equation were used to solve the temperature dependent emission spectral properties for 3.3 nm PbSe quantum dot doped liquid core fiber under different fiber length and doping concentration,considering the effect of the temperature on the parameters.It is found that the spectral peak position shifts to the red in a similar red shift rate with the temperature increasing,in the case of different fiber length.For the longer fiber,the spectral peak intensity decreases in a larger decline rate.In the case of different doping concentration,with the temperature increasing,the spectral peak position shifts to the red in a similar red shift rate,and the spectral peak intensity decreases in a similar decline rate.

    • 摘要: 组建了一套基于液芯光纤的激光诱导荧光食用油鉴别装置。研究了不同液芯光纤长度对食用油激光诱导荧光光谱的影响,分析了不同种类食用油激光诱导荧光光谱之间的差异。八种食用油共320份样本荧光数据在1m长液芯光纤内采集,采用主成分分析方法对食用油荧光数据进行降维处理,利用偏最小二乘判别分析(PLS-DA)方法建立食用油种类的鉴别模型。结果表明,使用液芯光纤后,食用油荧光强度得到较大的增强。随着液芯光纤长度增加,食用油荧光特征峰逐渐增加并且食用油的激光诱导荧光光谱会产生红移现象,当液芯光纤长度超过80 cm后,红移趋于饱和。不同食用油的荧光光谱形状差异较大,可用于区分不同种类食用油。利用主成分1和主成分2绘制的主成分得分图显示,不同种类食用油呈现很好的聚集。当选用主成分数为10时,建立的PLS-DA食用油种类鉴别模型对训练集和预测集样本识别率均达到100%。说明本装置用于食用油种类的快速鉴别具有较高的准确性。%A laser-induced fluorescence detection set based on liquid core optical fiber was established in this study.Eight edible oils were discriminated by using this detection set combined with chemometrics method.The effect of length of liquid core optical fiber on laser induced fluorescence spectrum was explored,and the differences between the spectra of different edible oils were analyzed.The fluorescence spectra of 320 samples covering 8 types of edible oil were measured in 1 meter liquid core optical fi-ber.Principal component analysis was used in fluorescence data dimensionality reduction process.Partial least squares discrimi-nant analysis (PLS-DA)method was used to develop the identification model to distinguish edible oil species.The results showed that the oil fluorescence intensity is greatly enhanced when liquid core optical fiber was used.With the increase of liquid core op-tical fiber length,the peaks of laser induced edible oil fluorescence spectra increased and the fluorescence spectra will produce red shift.The red shift tended to a constant value when the fiber length was more than 80 cm.The fluorescence spectra of different edible oils were quite different,its can be used to distinguish different types of edible oil.Principal component scores chart were get using PC1 and PC2 of edible oils fluorescence data which result in a trend of certain gather of same type of edible oil.The recognition rates of PLS-DA model for the calibration set and prediction set were both 100%.The study shows that the devel-oped device in this study has high accuracy for identifying the edible oil species.

    • 摘要: We present a method of achieving a flat-top Brillouin gain spectrum (BGS) with a controllable bandwidth based on multiple-lines pump modulation in a CS2/CCl4 mixture liquid-core optical fiber. The influences of the pump spectrum separation, the intensity of each spectrum line, and the mixing ratio of core liquid media on the BGS are theoretically investigated, and the conditions of producing the flat-top BGS with an adjustable bandwidth are obtained. Results show that 2-9 spectral lines are generated based on single-frequency and multifrequency modulation using an intensity or phase modulator. The flat-top BGS with bandwidths of 50 MHz-2 GHz are obtained by controlling spectrum separation, the intensity ratio of each spectral line and CS2 volume fraction. This method has advantages of convenient operation and wide bandwidth range. It can be applied in Brillouin amplification with high gain and low distortion, and hence satisfies the requirements of weak signal detection and slow light systems.%提出在CS2/CCl4混合介质液芯光纤中利用多线抽运调制技术实现带宽可控平顶布里渊增益谱的方法,理论研究了抽运光谱线间距、谱线强度和芯液介质混合比对布里渊增益谱的影响,得到了带宽可控平顶增益谱的条件。结果表明,采用一个强度或相位调制器,基于单频和多频调制技术产生2-9条抽运光谱线,通过控制谱线间距和各谱线强度比,并改变CS2体积分数,获得了增益带宽在50 MHz-2 GHz范围内可控的平顶增益谱。该方法操作简便、带宽调控范围大,可用于高增益低畸变布里渊放大,满足微弱光信号探测和慢光系统的应用需求。
