本論文主要設計與製作分佈反饋式雷射，使能達到高頻操作的目標。為了使傳輸模組更簡單與成本降低，高速直調半導體雷射對於短中距離高速傳輸系統是非常重要的，其優點在於可以運用多通道的系統模組達到高速傳輸，並可套用分波多工使頻寬增加。
本論文以AlInGaAs/InP材料製作波長1310 奈米可高頻操作的DFB雷射，此材料具有較大差分增益且可高溫操作的優勢，目標是使雷射的旁模抑制比在不同操作條件下皆能維持在30 dB以上且雷射頻寬超過18 GHz。
量測製作完成的DFB雷射的輸出特性，當溫度在20℃時輸出光功率可達28.34 mW，差分斜率為0.42 mW/mA，弛張振盪頻率(fr)可在16 GHz以上。當溫度上升至40℃時，輸出光功率降至17.26 mW，差分斜率0.3384 mW/mA，弛張振盪頻率最高可達14 GHz。

In this thesis a high-speed directly modulated DFB laser is fabricated and analyzed for applications in optical transmitters of large data rate. For realizing compact and low-cost optical transmission over intermediate and long reach, high-speed directly modulated lasers (DMLs) are indispensable. The high-speed DMLs of different wavelengths can be combined with a wavelength divided multiplexer to increase the transmission bandwidth.
We fabricated the high-speed DFB lasers based on AlInGaAs/InP material system and the peak wavelength is around 1310 nm. The AlInGaAs materials have the merits of large differential gain and are good for high-temperature operation. The goal is to achieve > 30 dB side-mode suppression ratio (SMSR) and >18 GHz 3-dB bandwidth over a wide range of operation conditions.
The fabricated lasers can output 28.34 mW with a slope efficiency of 0.4181 mW/mA and a resonant frequency (fr) up to 16 GHz at 20℃. When the temperature rises to 40℃, the output power decreases to
17.26 mW and the slope efficiency and the resonant frequency are 0.3384 mW/mA and 14 GHz, respectively. Good single-mode stability with > 30 dB SMSR can be obtained.
