本論文是利用數值模擬的方式來探討雙光注入半導體雷射系統的非線性動態，主要是透過固定一支主雷射的注入強度以及其頻率而改變另一支可調式雷射的注入光強度和頻率來分析整理所得到的動態，我們由微波譜上來判斷這些動態並且模擬出雙光注入半導體雷射非線性動態地圖。而在所得到的雙注入動態地圖當中，選取固定端雷射固定在單注入地圖穩定鎖住區域所得到大範圍的週期一動態地圖來進行分析，研究其產生週期一動態的原因。和單注入系統比較起來，我們可以利用這種方式產生的週期一動態得到高頻率的微波光子訊號而不會因進入到其它動態受到限制。

This study investigates the variation of dynamics in an optically injected semiconductor laser subject to a second optical injection through numerical simulation. Different dynamical states are identified by analyzing their time evolution, optical spectra, and microwave spectra. In particular, the analysis of microwave spectra is adopted to obtain mappings of dynamical states to demonstrate the variation of dynamic globally. Under proper combination of both injection condition, mappings showing only period-one dynamics are possible over a broad range. Such a characteristic offers a solution to generate high-frequency microwaves without the possibility of the system entering into other dynamical states as compared with the laser system subject to only one optical injection.
