Abstract: 光通訊在我們的日常生活中隨著對寬頻的要求而變的越來越重要,利用微機電技術為基礎製做的光學微鏡面切換器,由於其操作頻率和可靠性高的特性可以廣泛應用在光通訊分波多工技術的波長選擇切換器中。
本論文探討的是在1 x N2波長選擇切換器中的通道間響應現象,以傅氏光學、光電電磁學為理論基礎建構出模擬模型再經由電腦模擬來分析,並且利用實際實驗的結果來支持模擬模型的正確性。除了分析通道間響應的物理意義之外,由於通道間響應的現象在光通訊中即為信號雜訊,所以本論文嘗試利用旋轉準直器的方式,使輸入端光纖和輸出端光纖的位置不會順著光柵的色散方向,以達到壓抑通道間響應造成的信號雜訊之目的。
  另外本論文也利用模擬分析了自由空間中波長選擇切換器的色散特性,還有探討利用微鏡面切換器之波長選擇切換器當作光信號衰減器的可能性。
Optical communication becomes more and more important due to the requirement of broadband in our life. MEMS micromirror switches are generally applied in wavelength-selective switch of WDM system with their high performance and high operation frequency.
In this thesis, the inter-channel response in a MEMS 1 x N^2 WSS is investigated by the simulation, and the theoretical model is based on Fourier optics and EM wave optics. We also have experiment data to support the accuracy of simulation results. In addition to analyse the physical meaning of the inter-channel response, we attempt to find a simple solution to suppress the inter-channel response in a 1 x N^2 WSS. It can be achieved by rotating the 2D collimator array such that no output port is aligned with the input port along the dispersion direction, because the inter-channel response is undoubtedly undesirable for optical communication.
The dispersion characteristic in free-space MEMS WSS, and the possibility about MEMS WSS can be used as VOA , are also investigated by simulation in this thesis.
