For long - haul high bit rate trunk line optical fiber communication system and metro optical fiber network, a semiconductor optical amplifier ( soa ) is the most promising component due to its all kinds of properties and small dimension, compactiveness, low drive voltage, such as in optical network solutions, polarization - insensitive semiconductor optical amplifier ( pisoa ) is a popular candidate as optical gates. but the polarization - insensitivity over large wavelength range is requested. the purpose of this thesis is to develop a soa which is polarization - insensitive and has large 3db bandwidth
隨著寬帶傳輸和寬帶接入以及全光網的組建和發展，大帶寬偏振不靈敏半導體光放大器（ semiconductoropticalamplifier ， soa ）由於其易於與其它器件集成，體積小，具有快的動態增益響應，非線性好，飽和輸出大，可實現無損操作等特點，在光通信網路中，成為光纖通信發展，全光網組建以及wdm 、 tdm技術成熟的關鍵部件之一，其中偏振不靈敏和大的3db帶寬是性能優良soa的重要指標，也是制備的技術難點。
