摘要
开发设计了三种适用于光波导自动对接耦合的调芯方案:半值法、质心法、遗传法.完成了自动对接系统样机.通过了两类波导-光纤自动端面对接的实测.结果表明,该自动对接系统具有高效率低损耗对接的良好性能.
Three auto-aligning methods are designed, which are called the half value method, the harycenter one and the one based on genetic algorithm （GA）,respectively. The auto-aligning system model is completed. Taking single mode fiber as standard waveguide,the experiment and the results show the average end-coupling losses are less than 0. 1 dB,and the standard deviations are less than 0.012 dB at the wavelength 1310 nm and 1550 nm,respectively. This process only needs 2 minutes. When it comes to the experiment of fiher-SiO2 waveguide,the results suggest the average end-coupling losses are not more than 0.15 dB, and the standard deviations are less than 0. 025 dB at the wavelength 1310 nm and 1550 nm, respectively. The whole process is accomplished within 8 minutes. It shows that the methods and system have good performances.
