| 摘要: |
| 用钛内扩散和质子交换相结合的方法制得了光波导偏振器，这一偏振器由在不连续的扩钛波导中嵌入一段质子交换波导形成。本文讨论了一些资料中报道的检测方法，并对测量集成光波导偏振器提出了一个新方案，该方案测得的偏振器消光比大于52.5dB. |

| Abstract: |
| Integrated optical polarizers have been fabricated by using titanium indiffusion in conjunction with proton exchange. The polarizer consists of Ti-diffused channel waveguide with a short discontinuity fi1led with proton-exchanged waveguide. In this paper we have discussed the measuring methods which were reported in some refernces and proposed a novel design for charactering the integrated optical polarizers. While using this setup the polarizer fabricated in our laboratory exhibited polarization extinction ration of >52.5db. |
