摘要
用扩钛和质子交换相结合的方法在ｘ切ｙ传ＬｉＮｂＯ３衬底上制成了ＴＭ模集成光波导偏振器。质子交换区域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－波导－光纤插入损耗３．５ｄＢ。
In this paper, the diffraction efficiencies of infinite conductivity multilevel grating is treated by solving Maxwell′s equations numerically. The diffraction efficiency problem is solved by using mode matching method. Many important optimization results for engineering design are obtained.
