摘　　要：本文介绍了一种用于测量有机聚合物光波导传输损耗的方法一液体耦合法.该方法针对传统滑动棱镜法在实验操作、测量精度方面的不足,利用折射率高于波导芯层的液体取代输出棱镜,实现与导波光的耦合,并以TLC2543 AD芯片为核心制作数据采集卡对光强信号进行采集,拟合出光强传输衰减曲线.与传统的方法相比,该波导损耗测量系统具有测量简便、结果准确等优点,具有良好的推广价值.In this paper, liquid-coupling, a method for measuring the transmission loss of organic polymer waveguide is presented . Because the traditional prism coupling method has some shortages in experiment operation and measrement precision, the liquid which has a higher refractive index than that of the thin film of the waveguide is used instead of an output prism in this method. The coupling of the waveguide light is achieved. A high precision data collecting system based on a TLC2543 chip is designed to collect optical intensity and fit the attenuation curve of the optical intensity. Compared with the traditional method, this waveguide loss measurement system has the features of simpliness, accuracy and etc. and is of good value to many applications.
