The so-called terahertz band of the electromagnetic spectrum falls in a spectral region where traditional electronic technologies fail to operate owing to the extremely short switching times required. In this paper, we demonstrate the design of three optical logic gates fabricated by three-dimensional printing, which can perform the OR, AND, and XOR logic operations at 130 GHz. In order to optimize our designs we used a finite element electromagnetic simulation. The amplitude spectra of the experimental measurements of the three devices are presented where good agreement between the numerical results and experimental data can be seen. These results lead to the possibility of building more complex logic circuits based on these three photonic logic gates.

通过三维打印制造的太赫兹频率逻辑门

电磁频谱的所谓太赫兹频带落在一个频谱区域，传统的电子技术由于所需的极短的切换时间而无法运行。在本文中，我们演示了通过三维打印制造的三个光学逻辑门的设计，这些逻辑门可以在130 GHz的频率下执行“或”，“与”和“异或”逻辑运算。为了优化我们的设计，我们使用了有限元电磁仿真。给出了这三种设备的实验测量的振幅谱，在数值结果和实验数据之间可以看到很好的一致性。这些结果导致基于这三个光子逻辑门构建更复杂的逻辑电路的可能性。
