本論文主要是研究半導體雷射遭受光注入與光回饋且操作在週期一非線性動態的物理特性，並觀察在不同操作條件下的微波頻率與微波訊號品質。由於週期一非線性動態具有以全光式產生光載微波訊號的特性，並且其微波頻率以及調制深度可藉由改變半導體雷射的操作條件而調整，因此對於全光式光訊號產生以及微波訊號處理有很重要的應用。本論文主要以光注入半導體雷射以及光回饋半導體雷射兩種方式，使半導體雷射激發出週期一非線性動態。雖然此兩種方式皆不需要任何高頻的電子元件來產生微波，但其微波品質受到雷射本身雜訊的影響，這將限制通訊系統的傳輸品質。本研究利用光回饋的方式將此兩種方式產生的週期一動態優化，可將雜訊抑制到原來的百分之一以下，甚至也可透過外加的光回饋將微波頻率調整到原來的兩倍以上。

In this dissertation, the characteristics of P1 dynamics, which include microwave noise and microwave frequency, using semiconductor lasers subject to optical injection and optical feedback are investigated. By using P1 dynamics, many applications, such as all-optical signal and microwave processing, can be achieved without any electronic components owing to the all-optical generation of microwave. However, on the account of intrinsic laser noise, the noise quality of P1 dynamics limits the applications. By introducing the part of laser output back to the laser, the noise quality can be improved by operated conditions. The noise quality can be optimized even to two orders of magnitude. Besides, the microwave frequency can be changed up the two times.
