Electro - optical curves for lc cells have been analyzed and it has been shown mat a large attenuation range and a shallow attenuation slope can be achieved simultaneously for a variable optical attenuator based on a parallel - aligned lc cell with an appropriate surface anchoring strength. as compared with the existing liquid crystal - based voa structure ( using two cascaded lc cells with a particular material ), the present structure is simple and has no special requirement for the lc materials
提出了基於弱錨定平行排列液晶盒的可變光衰減器（衰減范圍大、衰減曲線下降平緩以保證調節精度） ，與己有液晶型可變光衰減器結構（選用特定液晶材料、兩個液晶盒級聯結構）相比較，本論文提出的基於弱錨定平行排列液晶盒的可變光衰減器結構簡單，同時對于液晶材料無特殊要求。From these results, mz - type voa based on two 3db directional couplers was studied further, the characters comparison between single and cascaded mz - type voa were given. the reflection leakage voa do n ' t depend on high temperature stability as mz - type need, while the latter own much lower power consumption than the former
在此基礎上，進一步分析了帶有3db定向禍合器的mz型熱光voa的衰減特性和器件藕合參數的關系，並給出了單個voa和衰減波譜更平坦的級聯voa之間的特性對比。
