本篇論文是利用光注入半導體雷射產生非線性週期一動態，並利用此動態進行光電式微波混頻系統的研究，本系統只要一個半導體雷射作為主要元件。由於週期一動態具有小的線寬、頻率可調性高，可以做為一個高品質光電式微波訊號源。本系統不需要額外的電子式微波產生器以及光電轉換器作為微波訊號源，且可因而改善無線通訊與光纖通訊整合系統的架構成本與能量轉換效率。
為了探討雷射操作條件產生週期一動態的共振邊帶與外部調制產生的調制邊帶在系統中的重要性；本論文會在第三章討論微波頻率降頻，當一載有微波之光訊號注入雷射時，其光載波激發此雷射產生週期一動態，由於週期一動態之共振頻率與調制頻率不相同，且週期一動態不被調制頻率穩定鎖住，因而達成混頻，混頻後能得到調制頻率與共振頻率的差值，在系統輸出端得到較為低頻的微波頻率，最佳轉換效率約為15 dB。
第四章則討論微波頻率升頻，一載有微波之光訊號注入雷射，其光載波激發此雷射產生週期一動態，藉由週期一動態產生超高頻共振頻率，可得調制頻率與共振頻率的差值，由於共振頻率遠大於調頻率，在系統輸出端得到高頻的微波頻率。藉由本系統可以得到微波頻率由數GHz到數十GHz，且具約有10 dB轉換效率。
在降頻中，不同雷射操作條件產生的週期一動態具有不同的共振頻率與邊帶強度，根據研究，低光注入強度或高主副雷射頻率差具有較強的共振邊帶，因此與調制邊帶混頻後能獲得較低的微波頻率與較好的轉效率；在升頻中，由於共振邊帶與調制邊帶兩者距離太遠，可以維持系統混頻後的轉換效率。

The purpose of this thesis is simulation study of photonic microwave mixing using nonlinear period-one dynamics of an optically injected semiconductor lasers. However, the semiconductor laser is operated at period-one dynamics, it provides a local oscillator frequency and executes photonic microwave mixing. Our system can detect up or down microwave signal with photonic microwave mixing. We demonstrate that by utilizing a modest over 50 GHz semiconductor laser which is operated at period-one dynamics state, the injected laser can generate the local oscillator frequency down to 5 GHz with high conversion efficiency about 10 dB. In this study, we also simulate the laser with 10 GHz modulation, which achieves 50 GHz microwave of output.
