| 摘 要： | 用扩钛和质子交换相结合的方法在ｘ切ｙ传ＬｉＢｎＯ３衬底上制成了ＴＭ模集成光波导偏振器。质子交换区位于扩钛波导的末端两侧。在质子交换区域Δｎｅ〉０，Δｎ０〈０，因此ＴＥ模辐射进入衬底。偏振器工作于１．３μｍ波长，消光比优于４７ｄＢ，光纤０－波导－光纤插入损耗３．５ｄＢ。

| Abstract: | TM-Pass integrated optical waveguide polarizers have been made in x-but ,y-propagating LiNbO3 using Ti indiffusion in conjunctio with proton exchange. The two exchanged regions are adjacent to the Ti indiffused waveguide on both sides and at the output end of the sample. In the proton-exchanged regions, Δne>0, Δn047 dB and fiber-waveguide-fiber excess loss is 3.5 dB. |
