摘    要:基于双光抽运探测模型,利用偶氮苯聚合物光致异构和光致双折射效应,建立了全光逻辑门的理论分析模型,提出了一种新颖的全光逻辑门设计方案.该方案基于输入抽运光和信号光的强度或偏振态,设计了“与”门、“或”门、“异或”门和“异或非”门等基本功能的全光逻辑门.以掺杂分散红1(DR1)的聚甲基丙烯酸甲酯(PMMA)薄膜为样品进行实验,得到了比较好的逻辑门运算实验结果,与理论分析相符合.

关 键 词:全光逻辑门  光致异构  光致各向异性

Abstract:Based on the photoisomerization and photoinduced birefringence in azo-containing polymers, a theoretical model for all-optical logic gates is developed and a novel scheme of all-optical logic gates using pump-probe technique is presented theoretically and realized experimentally. The all-optical logic AND, OR, XOR and XNOR gate operations have been demonstrated experimentally based on the modulation of intensity or polarization of the pump beam and signal. The experimental results show a good performance, which are in agreement with the theoretical prediction.
Keywords:all-optical logic gates   photoisomerization   photoinduced anisotropy
