本篇論文主要討論光互注入系統，此系統被應用在很多層面上，像是生物神經溝通上以及通訊上面的應用，通訊方面是為了取代單向光注入無法被積體化的缺點，生物方面則是有觀察到類似的非線性動態，因此以雷射系統來研究非線性行為，把雷射比擬成兩個細胞。互注入系統能改變的參數很多例如兩台雷射的頻率差、兩台雷射的互注入強度、延遲時間、雷射參數等等，大多數的論文研究方向以對稱的雷射系統做討論，近期有人研究不對稱的互注入強度，但是對於延遲時間比較少有相關論文，不對稱的延遲時間在各個領域皆有被研究過，像是生物神經、電的振盪器等等，因此為了完善互注入系統，探討不對稱的延遲時間是必須的。本篇針對光譜及動態地圖做主要討論，研究延遲時間的影響，以及針對穩定鎖住態以及週期一動態做更細節的研究，比較對稱延遲時間與不對稱延遲時間會造成什麼影響，

We focus on a mutually coupled laser system which is applied in many aspects like neural network and communication system. In communication system, we research on photonics integrated circuits (PIC) to enhance higher stability. There are many parameters can be changed in mutual injection system like detuning frequency and delay time between two lasers, mutual injection parameter, laser parameters, etc.
Much previous investigation emphasizes on symmetric system. Recently, some researchers study about the asymmetric injection intensity; however, investigation with asymmetric delay time is rare. The asymmetric delay time system has been researched in many fields like neural network and electronic oscillator. Therefore, to complete the mutual injection system, we study effects of asymmetric delay time. Our thesis shows dynamic maps and optical characteristics with asymmetric delay time; in addition, period-one and stable locking dynamic are the main discussion.
