我们报告了一种简单的不使用傅里叶变换系统的串行到并行转换方法。该方法是利用非线性波与参考脉冲的混频直接提取倾斜输入信号的窄时间范围。从理论上证明了该方法受非线性材料弛豫时间的影响较小。我们使用自组织量子阱材料实验证明了我们的方法，并证实T-bits/s脉冲可以清晰地转换为转换速率为140 GHz的空间模式。
We report a simple method of a serial-to-parallel conversion that does not use a Fourier-transform system. The method is based on directly picking up a narrow temporal range of the skewed input signal by using a nonlinear wave mixing with the reference pulse. We show theoretically that the pick-up method is less influenced by the relaxation times of the nonlinear material. We demonstrate our method experimentally using a self-organized quantum-well material, and confirm that T-bits/s pulses are clearly converted into spatial patterns with conversion rates of 140 GHz.
