摘要：

We propose AND,NOR,and XNOR logic gates realized simultaneously for 40-Gb/s networks,in which the realization of NOR and XNOR logic gates using only MgO-doped periodically poled lithium niobate(MgO:PPLN) is reported.In our configuration,we exploit broadband quasi-phase matching(QPM) cascaded second harmonic and difference-frequency generation(cSHG/DFG),cascaded sum-frequency and differencefrequency generation(cSFG/DFG) in one MgO:PPLN,and the narrow band QPM sum-frequency generation(SFG) in another MgO:PPLN.The performance,including the quality-factor(Q-factor) and extinction ratio(ER),of the proposed multifunctional logic device is also simulated.
