本篇論文的內容主要分為三部份。第一部份內容著重在準相位匹配二倍頻轉換的效率分析,我們使用以明確式有限差分為基礎的光束傳播法計算波導內準相位匹配倍頻轉換的效率,並將結果與塊材中的倍頻轉換效率作一個比較。其次,我們探討以加電場極化反轉法製作週期性鈮酸鋰晶體的機制,包括一套靜電場分析及一個提供動態反轉機制的模型。最後,我們研究實驗架構配置及不同外加電場對於製作品質的影響,並展示我們所製作出的週期性區域反轉結構,週期可達6.8μm,且有效長度可達2mm。
This dissertation is distributed into three parts. In the first part we emphasize on the analysis of the efficiency of quasi phase-matched second harmonic generation (SHG).We use the explicit finite-difference beam propagation method to compute the efficiency of SHG in a waveguide , and compare it with that in a bulk.
Second, the domain inversion of periodically poled Lithium Niobate (PPLN) during electric field poling is studied, including an analysis of static electric field and a model which describes the dynamic evolution of domain inversion.
Finally, the effects of experiment setup and different poling electric field on the quality of PPLN is studied , and PPLN with period equal to 6.8μm and effective length larger than 2mm is demonstrated
