針對目前衍射光柵器件在損耗、偏振敏感性等方面的不足,本文對金屬反射型以及內全反射型凹面光柵的偏振相關的衍射特性進行了矢量分析,並基於混合衍射方法提出了更為準確有效的優化設計方法。Based on this simulation method, the following novel designs are developed : 1, the two - stigma design, which can reduce the aberrations and improve the imaging of the grating ; 2, the flat - field design, which can omit the output waveguides and make an edg easier tc fabricate ; 3, the passband flattening design, which can relax the requirements on wavelength control for lasers and filters in a wdm system ; 4, the reduced back - reflection design, which guarantees very little reflection light back into the input channel and improves the feature of the return loss
本論文以用於光通信中的平面集成蝕刻衍射光柵為研究對象,具體的分析了的它的工作原理和設計思想,並給出了設計中的經驗和方法。器件設計后需要進行性能計算和模擬以減小復雜的集成光器件製作試驗,本論文描述了計算蝕刻衍射光柵比較準確的模擬方法,其結果能夠很好的接近實際情況。基於這樣的模擬計算方法,本論文提出了改進蝕刻衍射光柵設計的幾種方法: 1
