摘 要

本論文是以數值模擬的方式探討半導體雷射遭外部光注入後之雷射參數對於週期一震盪之影響，由於週期一震盪的光譜特性與頻率轉換有相似之處，所以本文主要探討各種雷射參數對於非線性動態圖、頻率轉換距離、旁模必v差、轉換效率、穿透率效率的影響，並評估週期一震盪是否適合做為頻率轉換器。使用光注入的方式改變主副雷射光頻差 ，以及注入副雷射的必v大小 ，來描繪出雷射的非線性動態圖，搭配改變雷射的偏壓電流 ，以及雷射本質參數 、 、 ， 的大小，來觀察雷射輸出動態的變化。

ABSTRACT

A numerical study on effects of laser parameters on period-one oscillations of optically injected semiconductor lasers is presented in this thesis. In this study, nonlinear dynamics、frequency separation、intensity difference、conversion efficiency、transmission efficiency as a function of laser parameters are investigated and discussed to assess suitability for frequency converter due to period-one oscillations spectrum characteristic is similar to frequency conversion. Nonlinear dynamics of an optically injected semiconductor laser is mapped as a function of injection parameter (ξ) and detuning frequency (f). Variation in the normalize bias current ( ) and intrinsic parameters ( 、 、 ， ) are observed have some effects on the dynamics of the system.
