本論文利用矽基液晶元件(Liquid Crystal on Silicon, LCoS device)來做為空間光調變器以此來進行1×9多波長選擇開關的設計與研究。
在進行波長選擇開關的設計中,本論文首先使用Zemax光學模擬軟體進行1×9多波長選擇開關的設計、模擬與性能優化,並分別針對不同接收端架構包含一維接收端架構(1×9),與二維接收端架構(5+4,3×3),進行研究與比較。續而依據軟體模擬結果進行1×9多波長選擇開關之實現,並針對使用矽基液晶元件之光調變器進行切換設計與特性量測。最後藉由使用電光調變器上載2.5Gbps訊號至可調式雷射光源,對本論文所實現之1×9多波長選擇開關進行數據傳輸測試。
從系統損耗之分析得知,本論文實現之1×9多波長選擇開關其損耗功率依不同波長之切換,約在15.52dB至16.79dB之間。從數據傳輸測試的眼圖量測結果,各接收光纖所接收到的每一波長,其誤碼率皆遠小於〖10〗^(-12)。
In this thesis, a Liquid Crystal on Silicon (LCoS)-based device was used as a Spatial Light Modulator (SLM) to experimentally implement a 1×9 Wavelength Selective Switch (WSS).
The design, simulation and performance optimization of 1×9 WSS system was evaluated through ZEMAX ray tracing simulation program, The system design of WSS using three- dimensions dynamic blazed grating with different receiver architecture including one-dimensional (1×9), and two-dimensional (5+4 and 3×3) layouts have been simulated and compared. From the simulation results, a 1×9 WSS system based on two-dimensional (3×3) receiver architecture was experimentally implemented. The wavelength selection of the implemented 1×9WSS system based on LCoS SLM was designed as well as the fundamental switching properties of LCoS device was also measured. A digital transmission test at a data rate of 2.5Gbps was applied to evaluate the system performance.
According to the experimental measurements, the system light loss were analyzed and the results shown that depending on the selection of different wavelength, the 1×9 WSS system has a light loss between 15.52dB and 16.79dB. In the digital transmission test, the bit error ratio (BER) of each wavelength received at the output fiber ports estimated from the measured Q factor of eye diagrams were all less than 10-12.
