| 摘 要： | 利用数码相机对离子交换平面玻璃光波导传输线进行数字成像，根据传输线上的光强分布拟合出光强传输衰减曲线，计算出波导的传输损耗.对光波导进行退火处理，研究了波导退火前后的传输损耗特性.退火后0阶模式下传输损耗由2.148 9 dB·cm－1降为0.746 0 dB·cm－1.结果表明，波导的传输损耗是随着模阶数的增加而递增，适当的退火处理明显改善了离子交换波导的质量. |

| Abstract: | The digital photographs of propagation lines of ion-exchange planar glass optical waveguides were taken by a common digital camera.According to the profile of light intensity of propagation lines,the attenuation curves were fitted and the propagation losses of the waveguides were calculated.The waveguides were treated by annealing process,and propagation losses properties were studied before and after annealing,respectively.The results show that the loss of waveguide increases with the mode.The loss in 0 mo... |
