我们展示了一个全光半加法器的两个串行数据流，同时产生和进位输出按位相加。该模块仅使用两个非线性光学元件执行所需的XOR和AND运算。在周期性极化的锂酸盐波导中的差频产生用作与门，并且在半导体光放大器中的交叉增益调制用于产生XOR输出。报告了RZ数据的无错误操作。
We demonstrate an all-optical half adder for bit-wise addition of two serial data streams that simultaneously generates Sum and Carry outputs. The module performs the required XOR and AND operations using only two nonlinear optical elements. Difference Frequency Generation in a periodically poled lithium niobate waveguide serves as the AND gate and cross-gain modulation in a semiconductor optical amplifier is employed to generate the XOR output. Error free operation for RZ data is reported.
