基于二维光子晶体非线性效应的全光逻辑门OACSTPCD
All-optical logic gate based on nonlinear effects of two-dimensional photonic crystals
基于光子晶体非线性效应和线性干涉效应设计了全光异或、非和与逻辑门.应用反演定理拆分较复杂逻辑表达式,通过级联组合设计了全光或非门和四输入与门逻辑器件.本文利用时域有限差分法进行仿真模拟计算,对非线性环形腔的耦合特性进行了分析,然后在信号波长为 1.47 μm条件下设计了上述逻辑器件,且通过可扩展输入端可设计出更多输入的器件.分析了信号功率对四输入与逻辑器件逻辑功能的影响.结果表明信号光源功率在 1.1 W/μm2 到3.4 W/μm2 之间时,输…查看全部>>
All-optical XOR,NOT and two-input AND logic gates are designed based on the nonlinear effect and linear interference effect of photonic crystals.The complex logic expressions are divided by inversion theorem,and all-optical NOR gate and four-input AND gate logic devices are designed by cascade combina-tion.In this paper,the Finite-Difference Time-Domain(FDTD)method is used for simulation,and the coup-ling characteristics of nonlinear annular cavities are ana…查看全部>>
