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 sec- ond harmonic and difference-frequency generation （cSHG/DFG）, cascaded sum-frequency and difference- frequency generation （cSFG/DFG） in one MgO：PPLN, and the narrow band QPM sum-frequency genera- tion （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.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.
