本篇論文主要探討光互注系統中的雷射光譜與雷射動態行為，在光互注系統中與光注入系統中有最大的差別在於雷射動態不只受限於雷射強度ξ_m、兩雷射間的頻率差Ω、還有因兩個雷射間距造成的延遲時間τ_f。在本篇論文中，我們固定延遲時間為22ps去觀察不同的非線性動態與動態地圖。在光互注系統下的動態地圖，我們觀察到許多與光注入系統相同的雷射非線性動態，如:穩定鎖住態、週期一動態、類週期動態、混沌動態。而本篇論文主要是觀察光互注系統中的雷射動態的光譜與微波譜並進行特性分析，因為我們想要比較兩個系統中相同的雷射非線性動態是否有相同的動態行為。

We study the spectral and dynamical behavior of two mutually delay-coupled semiconductor lasers. Unlike the case of unidirectional optical injection, the behavior of mutually delay-coupled lasers depends critically on a coupling delay time τ_f, a coupling strength ξ_m and a detuning frequency Ω between the lasers. In this thesis, we report rich nonlinear dynamics of the two mutually delay-coupled lasers with a coupling delay time≈22 ps in terms of the coupling ξ_mand the frequency detuning Ω. These dynamics including stable locking dynamics, period-one dynamics, quasi period dynamics, and chaos. Furthermore, we compare different dynamical behaviors between unidirectional optical injection and mutually delay-coupled lasers.
