以光傳遞訊息的日漸普及至積體光學元件益見其重要，而一日千里的製程技術使積體化元件日漸縮小，並也漸適於光子晶體波導元件的發展。循傳統波導元件Mach-Zehnder干涉儀式光塞取多功架構，改以線形光子晶體缺陷取代傳統導光波導，而處於晶體結構本身能隙內的電磁波模態受到強大的控光能力使元件面積大幅縮小，也因異於傳統波導在相對較高介電常數物質中傳導，光子晶體波導能設計成在較低介電常數物質內傳導，如此減少了物質本身的色散問題及非線性問題所帶來的困擾﹙但光子晶體結構使波導色散影響大幅提昇。﹚照相同於傳統波導布拉格反射濾波器結構於光子晶體，因高折射率比亦造成了過大帶止頻帶而不適用於反射式波長多功系統中。論文中以傳統波導耦合原理為基礎，設計了適用於波長多功的窄頻帶止濾波器，並分析各種結構變化即影響，使率波器頻帶能任意做不同程度的調整；且以多級架構使濾波器方正化更適合作於波長多功系統，最後加至干涉儀架構中成為光塞取多功器，因為採用傳統干涉儀架構的光塞取多功器，也因此很容易經由多級串/並後成為多頻道的光塞取架構。
