本篇論文主要研究光注入系統所產生的眾多非線性動態，其中的非鎖住動態，擁有因主雷射注入會使得副雷射頻移並產生強度不對稱的邊帶的特性，利用此特性做光雙單調制邊帶轉換，能用將轉換前SRR = 0 dB的光雙調制邊帶訊號，轉換成SRR有20 dB的光單調制邊帶訊號，可望能改善radio over fiber (RoF)系統傳遞光訊號時，由於調制光訊號產生兩強度相等之調制邊帶所造成的能量消逝效應。且轉換時利用主雷射的調制邊帶注入鎖定頻移後的副雷射，可以改善原先非鎖住動態頻率不穩的特性，並不會受到影響。此外可以透過調整操作條件控制非鎖住動態的再生主雷射與頻移的副雷射間的相對強度，使得轉換後的微波訊號強度有不同程度的放大，可達到20 dB以上的增益。且此系統對於欲轉換之光雙調制邊帶，其微波訊號頻率不穩定時，亦能在一定的範圍內對應，使其能成功的達成光雙單調制邊帶的轉換。

For radio-over-fiber (RoF) systems, direct and external modulation approaches typically generate optical double-sideband (DSB) modulation signals. Owing to chromatic dispersion in optical fibers, DSB signals lead to significant microwave power fading effect. To mitigate the microwave power fading effect, optical single-sideband (SSB) modulation signals are preferred. This study investigates an optically injected semiconductor laser operating at unlocking dynamics for DSB-to-SSB conversion. Compared with the optical DSB signals, such converted optical SSB signals exhibit greatly enhanced optical modulation depth, which indicates highly improved microwave power after photodetection. Therefore, the proposed system not only mitigates the microwave power fading effect but also enables microwave power amplification simultaneously.
