在本論文中，我們提出4×4陣列波導光柵與多重可調布雷格光柵濾波器之結構，實現一可調式可重組態光塞取多工器的光通訊網路節點，藉由陣列波導光柵之具有內插自由波長頻域特徵，本論文使用可調式布雷格光柵濾波，調整光柵中心波長訊號範圍，在光塞取多工器的其他通道和功能中，實驗驗證顯示沒有光訊號重疊與干涉問題產生，並且可利用陣列波導光柵之週期波長循環性質處理訊號程序，超過陣列波導光柵之實際硬體光通道數量，而且本研究使用微處理器控制加熱器之技術，可以精密調整布雷格光柵濾波之中心波長移位；事實上，可調式光塞取多工器，架構於陣列波導光柵與多重可調整布雷格光柵濾波已成功應用光塞取之功能，超過陣列波導光柵之多通道數量。

A 4x4 array-wavelength grating (AWG) with multiple tunable fiber Bragg gratings (FBGs) is presented to realize an unlimited multi-channels reconfigurable optical add-drop multiplexer (ROADM) node. By using the AWG interleaving wavelength characteristic, the proposal employs the tunable FBGs, which can modulate a wide range of Bragg wavelength without overlapping and/or interfering the spectra of the other channels signal, to carry out the add-drop function. Moreover, the AWG cycle wavelength property can be applied to process multiple channels signal beyond the number of AWG channels. The heater with microcomputer-controlling technique is realized to precisely modulate the Bragg wavelength for proving the shift of the Bragg wavelengths. As a result, a ROADM based on the AWG and multiple tunable FBGs has successfully added and dropped the multi-channels beyond the number of AWG channel.
