| 摘 要： | 设计了两种适用于光波导高精度自动对接耦合的调芯方案，从原理上克服了常规调芯过程中微变信号精确测试的困难。完成了调芯系统的光机电一体化、控制程序和接口界面。单模光纤作为标准波导的端面耦合自动凋芯试验显示，平均耦合损耗分别为0．075 dB(1310nm波长)和0．062 dB(1550nm波长)，相应的标准误差分别为0．0099 dB和0．0066 dB．调芯过程在2min内完成。单模光纤-单模波导-单模光纤的对接耦合实验结果表明，端面耦合损耗平均值分别为0．140 dB(1310nm波长)和0．109 dB(1550nm波长)，标准误差分别为0．0082dB和0．0107dB，调芯时间累计不超过8min。

| Abstract: | Based on analysis of the coupling theory, the two auto-aligning methods and programs are designed. Experiment results using single mode fiber as standard waveguide show that the average end-coupling loss is 0.075 dB, the standard deviation is 0.0099 dB at the wavelength 1310 nm, and is 0.0062 dB and 0.0066 dB at 1550 nm, respectively. A process only needs 2 min. When it comes to fiber-SiO 2 waveguide-fiber system, the average end-coupling losses are 0.140 dB and 0.109 dB, and the standard deviations are 0.0082 dB and 0.0107 dB, at 1310 nm and 1550 nm, respectively. The whole process is accomplished within 8 min. |
