本論文研製兼具增益之可重構光信號塞取多工器（ROADM），吾人提出兩類兼具增益之ROADM提供光網路應用，其一是單向可重構光信號塞取多工器，其二是雙向可重構光信號塞取多工器。
於實驗架構方面，我們以光纖光柵、光循環器、光纖放大器與光開關來完成。為避免光纖光柵內部串音效應造成信號劣化，須使用高反射率之光纖光柵，自製光纖光柵經退火後其反射率在99.5 %以上。吾人製作之可調光纖光柵範圍達17 nm，定波長光纖光柵誤差範圍小於0.04 nm。
在研製方面，吾人製作兩類兼具增益之ROADM；第一類內容是實際完成一台單向兼具增益之ROADM，頻道間距採用ITU-T建議的100GHz為1547.7-、1548.5-和1549.3 nm之光纖光柵，而第四通道採用可調光纖光柵以增加光塞取彈性，本塞取多工器的插入損失僅有4.3 dB，信號增益約14 dB；於10 Gb/s誤碼率實驗中，在傳輸25 Km且無使用色散補償光纖情況下，取出端的功率償付值僅有0.8 dB。此外吾人另設計三種單向多通道的架構，並分析其特性。第二類內容以實驗驗證一台雙向兼具增益之ROADM架構，得知其插入損失是5.3 dB且增益有17 dB。另外吾人亦設計一個雙向多通道架構，並分析其特性，最後我們對後續研究提出若干建議。

This thesis investigates several reconfigurable optical add/drop multiplexers (ROADM) with power compensation function. Here, we proposed both unidirectional and bi-directional ROADMs for optical networks applications. The ROADM is constructed by integrating fiber Bragg gratings (FBGs), optical circulators (OCs), optical switches (OSWs) and erbium-doped fiber amplifier. To avoid intraband crosstalk cause the signal deterioration, the home-made FBGs should have above 99.5% reflectivity after annealing. The tunable FBG with tuning range of 17 nm, while the wavelength fixed FBG has wavelength inaccurate less than 0.04 nm.
We manufacture two kinds of ROADM. Firstly, we investigate a unidirectional ROADM. The channel spacing is based on the ITU-T grid of 100 GHz in 1547.7-, 1548.5- and the 1549.3 nm. The fourth channel is to use a tunable FBG to increase the add/drop feasibility. Insertion loss and gain of the ROADM are 4.3 dB and 14 dB, respectively. In a 25 km standard fiber transmission without dispersion compensation, power penalty is only 0.8 dB at the dropped port for 10 Gb/s, bit error rate (BER) measurement. We also design another three kinds of unidirectional multichannel ROADMs and analyze their characteristics.
Secondly, we experimentally demonstrate a bidirectional ROADM including power compensation function. The insertion loss and gain of it are 5.3 dB and 17 dB, respectively. Moreover, we design another kind of bidirectional ROADM and analyze its characteristics. Finally, we conclude our achievements in this thesis and suggested future works.
