中文摘要 本研究發現利用光注入半導體雷射產生的穩定鎖住雷射作為全光頻率轉換系統,穩定鎖住半導體雷射的頻率轉換系統能比四波混合的頻率轉換系統擁有轉換頻寬提升、效率提升、平坦度較佳等優點,本篇論文將證明以光注入半導體雷射產生的穩定鎖住雷射作為全光頻率轉換系統擁有較好的格式透明度,能夠轉換各種格式的訊號,在振幅鍵控調變訊號部分,會證明平坦度差異造成訊號的好壞,以及證明能夠傳輸高速訊號;頻率鍵控調變訊號,說明訊號的載頻頻率差會因為濾波器的限制,而無法完美解調;另外討論調整穩定鎖住定半導體雷射的主副雷射頻率差以及注入強度,討論振幅、頻率以及相位鍵控調變訊號,在不同的穩定鎖住半導體雷射之下的訊號差異,並藉由轉換效率的靜態分析解釋訊號品質的差異;而且使用光注入的頻率轉換器直接解調相位控調變訊號,不需藉由麥克森干涉儀,就能夠直接解調相位控調變訊號。
英文摘要 All-optical frequency converters using stably injected-locked semiconductor lasers at four-wave mixing dynamics were studied experimentally. It was demonstrated that the proposed conversion system has certain advantages over solitary semiconductor lasers at four-wave mixing, such as enhanced conversion bandwidth, efficiency and flatness.
Due to the unique characteristic of modulation format transparency of the proposed system, frequency conversion for input signals with different modulation formats is analyzed. Effects of conversion bandwidth, efficiency and flatness on frequency conversion are investigated for different modulation formats.
