摘　　要：空间光调制技术广泛应用于阈值开关、高速光互连、光逻辑运算等领域,对光信号的实时快速寻址有极高的要求。与电寻址方式相比,光寻址采用并行寻址,速度快,分辨率高,具有更大的优势。但在实际应用中,如何实现快速稳定的光寻址成为空间光调制的关键。本文以Zn O薄膜作为光导层,构造光寻址液晶空间光调制器,更好地实现了对读出光光强和相位的二维空间分布的调制。The Spatial Light Modulation(SLM) technology has been widely applied to the fields of threshold switch, high speed optical interconnection and optical logic operations, which demands good performance on the real-time and fast optical signal addressing. Compared with Electro-Addressing SLM(EA-SLM), Optically-Addressing SLM(OA-SLM) shows great advantages of fast speed and high resolution by parallel addressing. Nevertheless, how to achieve fast and stable optically addressing is the key point in practice. Based on ZnO thin film as a photoconductive layer, Liquid Crystal OASLM(LC-OASLM) is designed and fabricated; the modulation of the readout light intensity and phase distribution in the two-dimensional space is achieved effectively.
