隨著下世代網路(Next generation networking, NGN)所發展出通用多重通訊協定標籤交換技術(Generalized Multi- Protocol Label Switching, GMPLS)中所需之自動交換光網路系統(Automatically Switched Optical Network, ASON)，可調式光塞取多工器(Reconfigurable optical add-drop multiplexer, ROADM)對ASON系統來說是一個不可或缺的元件，且高密度分波多工系統(Dense wavelength-division multiplex, DWDM)的信號在網路傳輸的管理下，其可協助網路管理員動態的管理客戶需求及所要的服務品質(Quality of Service, QoS)，並增加現有光纖線路的容量、減少或免除架設額外光纖線路的需要。
本論文研究ROADM以循環式陣列波導光柵(Array waveguide grating, AWG)和布雷格光纖光柵(fiber Bragg grating, FBG)為基礎架構，並且加入光循環器以及光纖光柵之架構擁有低串擾和不隨偏振擾動的特點，使得此架構值得被探討與研究。
在此論文中，提出了一種雙向性的ROADM，並且分析此架構的性能，實驗證實了所提出的實雙向性架構能夠把波長做更彈性的應用, 但此架構運用過多的元件數量而使插入損耗增加。

In response to the development of a next-generation networking (NGN), generalized multi-protocol label switching (GMPLS) technology is required for automatically switched optical network (ASON). Reconfigurable optical add-drop multiplexer (ROADM) is an indispensable device for the ASON, and the dense wavelength division multiplexed (DWDM) signals can be transmitted through the network under the management of the network administrator to configure dynamic customer needs and the desired quality of service (QoS). The ROADM can also increase the efficiency of utilizing the existing capacity of the optical fiber lines and can reduce or waive to set up additional optical fiber lines. This thesis studies a ROADM based on the arrayed waveguide grating (AWG) and the fiber Bragg grating (FBG) with hybrid optical circulator. The FBG based ROADM is attractive because of its low crosstalk and polarization insensitivity, and it is valuable to discuss and research it. In this thesis, the bidirectional ROADM is proposed. By analyzing the performances of the system experimentally, it is found the bidirectional structure can apply utilized wavelength signals more flexibly; however, the insertion loss increases due to too many components in this architecture.
