在光通訊系統中，關鍵元件之一就是單色光源。在系統積體化、微小化的趨勢下，單一晶片上使用多波長的單色光源作為訊號傳遞，通常須將多道雷射光源構裝在一起，使得製程複雜同時提高製作成本，此外多雷射構裝也造成元件過熱的問題。
因此我們提出利用矽波導的非線性現象，如：自相位調變、自由載子色散等產生連續頻譜再配合解多工元件控制輸出頻寬並分成多個單色光的頻道輸出，來解決多波長雷射整合所遇到的瓶頸。
本論文研究包含了矽波導的非線性理論與模擬，平面凹面光柵（解多工器）的原理與設計，以及元件的製作與量測分析。我們成功的將小尺寸的矽波導與平面凹面光柵整合在同一晶片上，並觀察到在高功率超短脈衝雷射的激發下，矽波導因非線性現象所產生的連續頻譜，由解多工器分成高達15個頻道輸出。此研究成功實現積體化多道單色光源的產生，並展現出其於晶片上脈衝塑形應用的可能性。
