我们提出了一种基于光子芯片的全光异或(XOR)门，用于在高度非线性的色散工程硫化物(As2S3)平面光波导中通过四波混频实现相位编码光信号。实现了40Gbit/S差分相移键控光信号的无差错异或运算，且没有功率损失。通过对160Gbit/S DPSK信号实现异或门，突出了该方法的有效性和宽带运算。
We demonstrate a photonic chip-based all-optical exclusive-OR (XOR) gate for phase-encoded optical signals via four-wave mixing in a highly nonlinear, dispersion-engineered chalcogenide (As2S3) planar waveguide. We achieve error-free, XOR operation for 40 Gbit/s differential phase shift keying (DPSK) optical signals with no power penalty. The effectiveness and broad bandwidth operation of our approach is highlighted by implementing an XOR gate for 160 Gbit/s DPSK signals.
